koninklijke philips electronics n.v. 2004. all rights reserved. product data sheet rev. 01 16 november 2004 9 of 42 philips semiconductors TDA9881 alignment-free vision and fm sound if pll demodulator the afc signal is derived from the corresponding downcounter stop value after a counting cycle. the last four bits are latched and the digital-to-analog converted value is given as current at pin afc. 8.7 video demodulator and ampli?er the video demodulator is realized by a multiplier which is designed for low distortion and large bandwidth. the vif signal is multiplied with the in phase signal of the vif pll vco. the demodulator output signal is fed into the video preampli?er via a level shift stage with integrated low-pass ?lter to achieve carrier harmonics attenuation. the output signal of the preampli?er is fed to the vif agc detector (see section 8.3 ) and in the sound trap mode is also fed internally to the integrated sound carrier trap; see section 8.8 . the differential trap output signal is converted and ampli?ed by the following postampli?er. the video output level at pin cvbs is 2 v (p-p). noise clipping is provided. 8.8 sound carrier trap the sound carrier trap consists of a reference ?lter, a phase detector and the sound trap itself. a sound carrier reference signal is fed into the reference low-pass ?lter and is shifted by nominal 90 degrees. the phase detector compares the original reference signal with the signal shifted by the reference ?lter and produces a dc voltage by charging or discharging an integrated capacitor with a current proportional to the phase difference between both signals, respectively to the frequency error of the integrated ?lters. the dc voltage controls the frequency position of the reference ?lter and the sound trap. thus the accurate frequency position for the different standards is set by the sound carrier reference signal. the sound trap itself is constructed of three separate traps to realize suf?cient suppression of the ?rst and second sound carrier. 8.9 sif ampli?er the sif ampli?er consists of three ac-coupled differential stages. gain control is performed by emitter degeneration. the total gain control range is typical 66 db. the differential input impedance is typical 2 k w in parallel with 3 pf. 8.10 sif agc detector sif gain control is performed by the detection of the sif voltage at the output of the sif ampli?er so that a constant sif signal is supplied to the single reference qss mixer. for an optimum adaption between the sif agc and the vif agc characteristics at 13 db picture-to-sound fm carrier ratio, the internal sif level is reduced. the integrated agc capacitor is charged or discharged for the generation of the required sif gain via a comparator. an additional circuit (threshold approximately 7 db) ensures a very fast gain reduction for a large increasing if amplitude step. 9397 750 13417 ?

gain controlled fm ampli?er and agc detector ? narrow-band pll. the intercarrier signal from the single reference qss mixer is fed to the input of an ac-coupled gain controlled ampli?er with two stages. the gain controlled output signal is fed to the phase detector of the narrow-band fm pll (fm demodulator). for good selectivity and robustness against disturbance caused by the video signal, a high linearity of the gain controlled fm ampli?er and of the phase detector as well as a constant signal level are required. the gain control is done by means of an in phase demodulator for the fm carrier (from the output of the fm ampli?er). the demodulation output is fed into a comparator for charging or discharging the integrated agc capacitor. this leads to a mean value agc loop to control the gain of the fm ampli?er. the fm demodulator is realized as a narrow-band pll with an external loop ?lter, which provides the necessary selectivity (bandwidth approximately 100 khz). to achieve good selectivity, a linear phase detector and a constant input level are required. the gain controlled intercarrier signal from the fm ampli?er is fed to the phase detector. the phase detector controls, via the loop ?lter, the integrated low radiation relaxation oscillator. the designed frequency range is from 4 mhz to 7 mhz. the vco within the fm pll is phase-locked to the incoming 2nd sif signal which is frequency modulated. the vco control voltage is superimposed by the af voltage. therefore, the vco tracks with the fm of the 2nd sif signal. thus, the af voltage is present at the loop ?lter and is typically 5 mv (rms) for 27 khz fm deviation. this af signal is fed via a buffer to the audio ampli?er. the correct locking of the pll is supported by the digital acquisition help circuit; see section 8.6 . 9397 750 13417 ?

af preampli?er ? af output ampli?er. the af preampli?er used for fm sound is an operational ampli?er with internal feedback, high gain and high common mode rejection. the af voltage from the pll demodulator is 5 mv (rms) for a frequency deviation of 27 khz and is ampli?ed by 30 db. by using a dc operating point control circuit (with external capacitor c af ), the af preampli?er is decoupled from the pll dc voltage. the low-pass characteristic of the ampli?er reduces the harmonics of the sound intercarrier signal at the af output terminal. for fm sound a switchable de-emphasis network (with external capacitor) is implemented between the preampli?er and the output ampli?er. the de-emphasis time constant with 50 m s or 75 m s depends on the fm carrier selection via pins fm0 and fm1; see t ab le 5 . the af output ampli?er provides the required af output level by a rail-to-rail output stage. a preceding stage makes use of an input selector for switching between the fm sound and mute state. switching to the mute state is controlled automatically, depending on the digital acquisition help circuit should the vco of the fm pll not be in the required frequency window. this is done by a time constant: fast for switching to the mute state and slow (typically 40 ms) for switching to the non-mute state. auto mute can be disabled via pin amute0; see t ab le 6 . 8.14 internal voltage stabilizer the band gap circuit internally generates a voltage of approximately 2.4 v, independent of the supply voltage and the temperature. a voltage regulator circuit, connected to this voltage, produces a constant voltage of 3.55 v which is used as an internal reference voltage. 8.15 logic the logic circuit detects the logic level at the logic ports vif0, qsso, fm0, fm1 and amute0 and controls the internal functions; see t ab le 4 to t ab le 6 . in the event that all logic ports are open-circuit (high-ohmic or cmos high level) tv standard ntsc with a vision carrier frequency of 45.75 mhz, an fm sound carrier frequency of 4.5 mhz, de-emphasis with 75 m s time constant and auto mute on is selected. table 4: vif frequency selection qsso vif0 vif frequency (mhz) no resistor at pin pin open-circuit 45.75 no resistor at pin pin connected to ground 38.9 2.2 k w resistor to ground at pin pin open-circuit 58.75 2.2 k w resistor to ground at pin pin connected to ground 38.0 9397 750 13417 ?

[3] this parameter is not tested during the production and is only given as application information for designing the receiver c ircuit. [4] loop bandwidth bl = 70 khz (damping factor d = 1.9; calculated with sync level within gain control range). calculation of the vif pll ?lter can be done by use of the following formula: , valid for d 3 1.2 , where: k o is the vco steepness or ; k d is the phase detector steepness ; r is the loop resistor; c is the loop capacitor; bl - 3db is the loop bandwidth for - 3 db; d is the damping factor. [5] v i(vif) = 10 mv (rms); d f = 1 mhz (vco frequency offset related to picture carrier frequency); white picture video modulation. [6] condition: luminance range (5 steps) from 0 % to 100 %. [7] s/n w(video) is the ratio of black-to-white amplitude to the black level noise voltage (rms value measured on pin cvbs). b = 5 mhz (b/g, i and d/k standard). noise analyzer setting: 200 khz high-pass and sc-trap switched on. [8] the intermodulation ?gures are de?ned for: a) f = 1.1 mhz (referenced to black and white signal) as b) f = 3.3 mhz (referenced to color carrier) as [9] modulation vestigial side-band (vsb); sound carrier off; f video > 0.5 mhz. measurements taken with saw ?lter m1963m (sound shelf: 20 db); loop bandwidth bl = 70 khz. [10] sound carrier on; f video = 10 khz to 10 mhz. measurements taken with saw ?lter m1963m (sound shelf: 20 db); loop bandwidth bl = 70 khz. [11] conditions: video signal, grey level and negative modulation. [12] ac load; c l < 20 pf and r l >1k w . the sound carrier frequencies (depending on tv standard) are attenuated by the integrated sound carrier traps (see figure 12 to figure 17 ; ? h(s) ? is the absolute value of transfer function). [13] the response time is valid for a vif input level range from 200 m vto70mv. [14] to match the afc output signal to different tuning systems a current source output is provided. the test circuit is given in figure 9 . the afc slope (voltage per frequency) can be changed by resistors r1 and r2. [15] the tolerance of the reference frequency determines the accuracy of the vif afc, fm demodulator center frequency and maximum fm deviation. [16] the intercarrier output signal at pin qsso can be calculated by the following formula taking into account the internal video signal with 1.1 v (p-p) as a reference: (rms) where: is the correction term for rms value, is the sound-to-picture carrier ratio at pins vif1 and vif2 in db, 6 db is the correction term of internal circuitry and 3 db is the tolerance of video output and intercarrier output v o(intc)(rms) . [17] to detect a logical 1 at pin qsso, no dc load at pin qsso is allowed. qsso = 0 will be done by the application of a 2.2 k w resistor between pin qsso and ground. [18] sif input level is 10 mv (rms); vif input level is 10 mv (rms) unmodulated. [19] measured with an fm deviation of 25 khz and the typical af output voltage of 500 mv (rms). for handling a frequency deviation of more than 55 khz, the af output signal has to be reduced in order to avoid clipping (thd < 1.5 %) by means of a resistor r x with external application at pin afd (see figure 20 and figure 21 ). [20] the lower limit of the audio bandwidth depends on the value of the capacitor at pin afd. a value of c af = 470 nf leads to f af( - 3db) ? 20 hz and c af = 220 nf leads to f af( - 3db) ? 40 hz. bl 3db C 1 2 p ------ k o k d r = d 1 2 -- - rk o k d c = rad v ------- ? ?? 2 p hz v ------ - ? ?? m a rad ------- ? ?? a im 20 v 0 at 4.4 mhz v 0 at 1.1 mhz ----------------------------------- ? ?? 3.6 db + log = a im 20 v 0 at 4.4 mhz v 0 at 3.3 mhz ----------------------------------- ? ?? log = v o(intc) 1.1 v (p-p) 1 22 ---------- 10 v isc () v ipc () ---------------- - db () 6 db 3 db + 20 ----------------------------------------------------------------- = 1 22 ---------- v isc () v ipc () --------------- - db () 9397 750 13417 ? koninklijke philips electronics n.v. 2004. all rights reserved. product data sheet rev. 01 16 november 2004 24 of 42 philips semiconductors TDA9881 alignment-free vision and fm sound if pll demodulator [21] for all s/n measurements the used vif modulator has to meet the following speci?cations: a) incidental phase modulation for black-to-white jump less than 0.5 degrees. b) qss af performance, measured with the television demodulator amf2 (audio output, weighted s/n ratio) better than 60 db (at deviation 27 khz) for 6 khz sine wave black-to-white video modulation. c) picture-to-sound carrier ratio pc/sc 1 = 13 db (transmitter). [22] calculation of the loop ?lter can be done approximately by use of the following formulae: the formulae are only valid under the following conditions: j 1 and c s >5c p where: k o is the vco steepness or ; k d is the phase detector steepness ; r is the loop resistor; c s is the series capacitor; c p is the parallel capacitor; f o is the natural frequency of pll; bl - 3db is the loop bandwidth for - 3 db; j is the damping factor. for examples, see t ab le 11 . [23] the pc/sc ratio is calculated as the addition of tv transmitter pc/sc 1 ratio and saw ?lter pc/sc 1 ratio. this pc/sc ratio is necessary to achieve the s/n w values as noted. a different pc/sc ratio will change these values. [24] measurements taken with saw ?lter g1984 (siemens) for vision and sound if (sound shelf: 14 db). picture-to-sound carrier ratio of transmitter pc/sc = 13 db. input level on pins vif1 and vif2 of v i(sif) = 10 mv (rms) sync level, 27 khz fm deviation for sound carrier, f af = 400 hz. measurements in accordance with ccir 468 . de-emphasis is 50 m s. [25] the qss signal output on pin qsso is analyzed by a test demodulator tda9820. the s/n ratio of this device is more than 60 db, related to a deviation of 27 khz, in accordance with ccir 468 . [26] measurements taken with saw ?lter g3962 for vision if (suppressed sound carrier) and k9350 for sound if (suppressed picture carrier). input level v i(sif) = 10 mv (rms), 27 khz (54 % fm deviation). [27] the value of c x determines the accuracy of the resonance frequency of the crystal. it depends on the used type of crystal. [28] pin ref is able to operate as a 1-pin crystal oscillator input as well as an external reference signal input, e.g. from the tuning system. f o 1 2 p ------ k o k d c p --------------- - = j 1 2r k o k d c p ---------------------------------- - = bl 3db C f o 1.55 j 2 C () = rad v ------- ? ?? 2 p hz v ------ - ? ?? m a rad ------- ? ?? table 11: examples to the fm pll ?lter bl - 3db (khz) c s (nf) c p (pf) r (k w ) j 100 10 390 5.6 0.5 160 10 150 9.1 0.5 table 12: input frequencies and carrier ratios description symbol b/g standard m/n standard unit vif carrier f pc 38.9 45.75 or 58.75 mhz sif carrier f sc1 33.4 41.25 or 54.25 mhz f sc2 33.158 - mhz picture-to-sound carrier ratio sc 1 13 7 db sc 2 20 - db 9397 750 13417 ? koninklijke philips electronics n.v. 2004. all rights reserved. product data sheet rev. 01 16 november 2004 25 of 42 philips semiconductors TDA9881 alignment-free vision and fm sound if pll demodulator fig 4. typical video signal levels on output pin cvbs (sound carrier off). fig 5. ripple rejection condition. 1.20 v 1.80 v 3.20 v white level 3.41 v zero carrier level black level sync level 001aab341 video 2 v (p-p) TDA9881 v p = 5 v v p (v) t (s) 5 100 mv f ripple = 70 hz 001aab339 9397 750 13417 ? koninklijke philips electronics n.v. 2004. all rights reserved. product data sheet rev. 01 16 november 2004 26 of 42 philips semiconductors TDA9881 alignment-free vision and fm sound if pll demodulator (1) v vagc is vif agc voltage and can be measured at pin vagc.

below 225 c (snpb process) or below 245 c (pb-free process) C for all bga, htsson..t and ssop..t packages C for packages with a thickness 3 2.5 mm C for packages with a thickness < 2.5 mm and a volume 3 350 mm 3 so called thick/large packages. ? below 240 c (snpb process) or below 260 c (pb-free process) for packages with a thickness < 2.5 mm and a volume < 350 mm 3 so called small/thin packages. moisture sensitivity precautions, as indicated on packing, must be respected at all times. 15.3 wave soldering conventional single wave soldering is not recommended for surface mount devices (smds) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. to overcome these problems the double-wave soldering method was speci?cally developed. if wave soldering is used the following conditions must be observed for optimal results: ? use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. ? for packages with leads on two sides and a pitch (e): C larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; 9397 750 13417 ? koninklijke philips electronics n.v. 2004. all rights reserved. product data sheet rev. 01 16 november 2004 38 of 42 philips semiconductors TDA9881 alignment-free vision and fm sound if pll demodulator C smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves at the downstream end. ? for packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves downstream and at the side corners. during placement and before soldering, the package must be ?xed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. typical dwell time of the leads in the wave ranges from 3 seconds to 4 seconds at 250 c or 265 c, depending on solder material applied, snpb or pb-free respectively. a mildly-activated ?ux will eliminate the need for removal of corrosive residues in most applications. 15.4 manual soldering fix the component by ?rst soldering two diagonally-opposite end leads. use a low voltage (24 v or less) soldering iron applied to the ?at part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 seconds to 5 seconds between 270 c and 320 c. 15.5 package related soldering information [1] for more detailed information on the bga packages refer to the (lf)bga application note (an01026); order a copy from your philips semiconductors sales of?ce. [2] all surface mount (smd) packages are moisture sensitive. depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). for details, refer to the drypack information in the data handbook ic26; integrated circuit packages; section: packing methods . [3] these transparent plastic packages are extremely sensitive to re?ow soldering conditions and must on no account be processed through more than one soldering cycle or subjected to infrared re?ow soldering with peak temperature exceeding 217 c 10 c measured in the atmosphere of the re?ow oven. the package body peak temperature must be kept as low as possible. table 13: suitability of surface mount ic packages for wave and re?ow soldering methods package [1] soldering method wave re?ow [2] bga, htsson..t [3] , lbga, lfbga, sqfp, ssop..t [3] , tfbga, vfbga, xson not suitable suitable dhvqfn, hbcc, hbga, hlqfp, hso, hsop, hsqfp, hsson, htqfp, htssop, hvqfn, hvson, sms not suitable [4] suitable plcc [5] , so, soj suitable suitable lqfp, qfp, tqfp not recommended [5] [6] suitable ssop, tssop, vso, vssop not recommended [7] suitable cwqccn..l [8] , pmfp [9] , wqccn..l [8] not suitable not suitable 9397 750 13417 ? koninklijke philips electronics n.v. 2004. all rights reserved. product data sheet rev. 01 16 november 2004 39 of 42 philips semiconductors TDA9881 alignment-free vision and fm sound if pll demodulator [4] these packages are not suitable for wave soldering. on versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. on versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. [5] if wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. the package footprint must incorporate solder thieves downstream and at the side corners. [6] wave soldering is suitable for lqfp, qfp and tqfp packages with a pitch (e) larger than 0.8 mm; it is de?nitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. [7] wave soldering is suitable for ssop, tssop, vso and vssop packages with a pitch (e) equal to or larger than 0.65 mm; it is de?nitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. [8] image sensor packages in principle should not be soldered. they are mounted in sockets or delivered pre-mounted on ?ex foil. however, the image sensor package can be mounted by the client on a ?ex foil by using a hot bar soldering process. the appropriate soldering pro?le can be provided on request.
