The maximum total system identification time `on' for a channel change is equal to maximum value of tident(on) plus tI2C(read-out). The maximum total system identification time `off' for a channel change is equal to maximum value of tident(off) plus tI2C(read-out). The fast mode is proposed mainly during search tuning, program or channel select. If the channel is selected, the identification response should be switched to normal mode for improved reliability. However due to the transition from fast to normal mode, the identification bits are not valid for one integrator period. Therefore the transmitter mode detected during the fast mode has to be stored before changing to normal mode. The storage has to be kept for two seconds (maximum value of tident(on) in the normal mode) from the moment of transition. The identification can now operate in the normal mode until the next tuning action. 3.

To achieve good selectivity, linear Phase Detectors (PDs) and constant input levels are required. The intercarrier signal from the input terminal is fed via high-pass filters and gain controlled amplifiers to the phase detectors. A carrier cancellation circuit placed before the amplifier for the second PLL is used to reduce the first sound carrier. The PD output signals control the integrated relaxation oscillators via the loop filters. The frequency range is approximately 4 to 7 MHz. As a result of locking, the oscillator frequency tracks with the modulation of the input signal and the oscillator control voltages are superimposed by the AF voltages. Using this method, the FM-PLLs operate as FM demodulators. The AF voltages are present at the loop filters and fed via buffers with 0 dB gain to the audio amplifiers. The supported standards and their characteristics are given in Table 1. Digital acquisition help A narrow-band PLL requires a measure to lock to the wanted input signal. Each relaxation oscillator of the three integrated PLLs (first and second sound carriers and pilot carrier) has a wide frequency range. To guarantee correct locking of the PLL with respect to the catching range, the digital acquisition help provides individual control until the VCO frequency is within the standard and PLL dependent lock-in window, related to the standard dependent carriers. It ensures that the oscillator frequency of the FM-PLL is within 225 kHz of the sound carrier to be demodulated. The pilot carrier frequency window is 150 Hz. The working principal of the digital acquisition help is as follows. The VCOs are connected, one at a time, to a down-counter. The counter start value is standard dependent and predefined for each of the three PLLs. After a given counting time the stop value of the down-counter is probed. If the stop value is lower (higher) than the expected value range, the VCO frequency is higher (lower) than the lock-in window. A negative (positive) control current is injected into the loop filter for a short time, thereby decreasing (increasing) the VCO frequency by a proportional value. If the stop value meets the expected value range, the VCO frequency is within the defined lock-in window and no control current is injected into the loop filter. TDA9873H In an endless circle the VCO of the next PLL will be connected to the down-counter and the described procedure starts again. The whole tracing as well as the counting time itself is derived from the external frequency reference. The cycle time is 256 s. Auto mute If a sound carrier is missed, acquisition pulses are generated when the NBPLL frequency leaves the window edges. To avoid noise at the audio output, an I2C-bus switchable mute-enable stage is built in. If auto mute is enabled via the I2C-bus, the circuit mutes immediately after the first acquisition pulse. If a sound carrier occurs (no further acquisition pulses), the mute stage automatically returns to active mode after 40 ms. If the first sound carrier is not present, the second audio channel will also be muted. Audio preamplifier The AF preamplifiers are operational amplifiers with internal feedback, high gain and high common mode rejection. The AF voltages from the PLL demodulators (small output signals) are amplified by approximately 34 dB. Using a DC operating point control circuit, the AF amplifiers are decoupled from the PLL DC voltage. The amplified AF signals are available at the output terminals and fed via external decoupling capacitors to the stereo decoder input terminals. Stereo decoder The input circuit incorporates a soft-mute stage which is controlled by the FM-PLL acquisition circuit. The auto mute function can be disabled via the I2C-bus. The AF output voltage is 500 mV (RMS) for 54% modulation, clipping therefore may occur at high over-modulation. If more headroom is required the input signal can be attenuated by 6 dB via the I2C-bus. A stereo adjustment (see Fig.6) is incorporated to correct the FM demodulator output voltage spread (see Table 19). If no I2C-bus adjustment is required (potentiometer adjustment or no adjustment) the default value should be 0 dB for B/G, M and D/K (2) standard. For the standards D/K (1) and D/K (3) the second sound carrier frequency is below the first sound carrier which results in a lower AF output level for the second sound carrier. In this state, a gain of +0.1 dB for D/K (1) and +0.2 dB for D/K (3) is preferred. 2000 Apr 04 7 Philips Semiconductors Product specification Multistandard dual carrier stereo sound decoder In the following dematrix, the modes stereo, mono and dual are processed for the different standards. The 6 dB level difference between B/G and M standard is automatically compensated in the dematrix, therefore no further level adaption is needed. De-emphasis is performed by two RC low-pass filter networks with internal resistors and external capacitors. The time constant is automatically switched to 50 s or 75 s according to the chosen standard. Due to some frequency response peaking of the FM demodulation, compensation is necessary. This is done by having a slightly larger time constant for the de-emphasis. All other settings such as AF switch, stereo channel adjustment values or default corrections have to be controlled via the I2C-bus depending on the identification or user definition. AF switch The circuit incorporates a single stereo and mono AF output. Using rail-to-rail operational amplifiers, the clipping level is set to 1.4 V (RMS) for VCC = 5 V. As well as the internal stereo decoder output signal, one external stereo and one mono input can be switched to the AF outputs. Both the mono and stereo outputs can be switched independent of the internal or external sources (see Tables 13 and 25). Fig.6 shows the switch configurations. A nominal gain of 0 dB for the signals from the external inputs to the outputs is built-in. Stereo/dual sound identification The pilot signal is fed to the input of a NBPLL. The PLL circuit generates the synchronized pilot carrier. This carrier is used for the synchronous AM demodulation to get the low-pass filtered identification signal. A Schmitt trigger circuit performs pulse shaping of the identification signal when the signal level is higher than the Schmitt trigger threshold. For smaller signal levels there is no AC output signal, thus protecting against mis-identification caused by spurious signal components. TDA9873H The identification stages consist of two digital PLL circuits and digital integrators to generate the stereo or dual sound identification bits, which can be read out via the I2C-bus. A 4 MHz crystal oscillator provides the reference clock frequency. The corresponding detection bandwidth is larger than 50 Hz for the pilot carrier signal, so that fpilot variations from the transmitter can be tracked in the event of missing synchronization with the horizontal frequency fH. However, the detection bandwidth for the identification signal is limited to approximately 1 Hz for high identification reliability. I2C-bus transceiver The TDA9873H is microcontroller controlled via a 2-wire I2C-bus. Two wires, serial data (SDA) and serial clock (SCL) carry information between the devices connected to the bus. The TDA9873H has an I2C-bus slave transceiver with auto-increment. To avoid conflicts in applications with other ICs providing similar or complementary functions, two slave addresses are available, selected on the pin MAD. A slave address is sent from the master to the slave receiver. In the TV sound processor family several devices are available. To identify the TDA9873H device, the master sends a slave address with R/W bit = 0. The slave then generates an acknowledge and the master sends the data subaddress 254 to the slave, followed by an acknowledge from the slave to the master. The master then sends the slave address with R/W bit = 1. The slave then transmits the device identification code 80H to the master, followed by an acknowledge NOT and a STOP condition generated by the master. Control ports Two digital open-collector output ports P1 and P2 provide external switching functions in the receiver front-end or IF demodulators. The ports are controlled by the I2C-bus (see Tables 22 and 23) and are freely programmable. 2000 Apr 04 8 Philips Semiconductors Product specification Multistandard dual carrier stereo sound decoder Power supply The different supply voltages and currents required for the analog and digital circuits are derived from two internal band gap reference circuits. One of the band gap circuits internally generates a voltage of approximately 2.4 V, independent of the supply voltage and 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. The AF reference voltage Vref is 1 V . Good ripple rejection is achieved with the external 2 CC capacitor Cref = 47 F (16 V) in combination with an internal resistor at pin 6. No additional DC load for 12VCC is allowed. TDA9873H Analog ground (AGND, pin 7) and digital ground (DGND, pin 27) should be connected directly to the IC. Pin 13 is internal analog ground. Power-on reset When a Power-on reset is activated by switching on the supply voltage or because of a supply voltage breakdown, the 117/274 Hz DPLL, 117/274 Hz integrator and the registers will be reset. Both AF channels (main and mono) are muted. The ports are in position HIGH. Gain stereo adjustment is 0 dB. Auto mute is active. For detailed information see Table 12.

Input level for IF intercarrier from an external generator with 50 source impedance, fmod = 400 Hz, 27 kHz deviation of audio references: level for SC1 is 50 mV (RMS), SC1/SC2 = 7 dB. S/N and THD measurements are taken at 50 s de-emphasis. 2. For higher input voltages a series resistor connected to pin 25 is recommended. 3. The tolerance of the reference frequency determines the accuracy of the FM demodulator centre frequencies, maximum FM deviation, pilot window width and pilot window mid-frequency error. 2000 Apr 04 14 Philips Semiconductors Product specification Multistandard dual carrier stereo sound decoder 4. Approximate calculation of the FM-PLL loop filter can be done using the following formula: 1 KO x KD 1 B L ( -3dB ) = ------ -------------------- 1.55 - --------------------------------------------------- CP 2 4R 2 x K O x K D x C P rad Hz with KO = VCO steepness -------- or 2 ------- V - V A KD = phase detector steepness -------- rad R = loop resistor. CS = series capacitor. CP = parallel capacitor. BL(-3dB) = loop bandwidth for -3 dB. Example for BL(-3dB) = 80 kHz: CS = 3.3 nF; CP = 680 pF; R = 5.6 k. TDA9873H 5. The lower limit of audio bandwidth depends on the value of the capacitors at pins 24 and 26. A value of CAF = 470 nF leads to BAF(-3dB) < 20 Hz and a value of CAF = 220 nF leads to BAF(-3dB) < 40 Hz. 6. S/N decreases by 4 dB if no second sound carrier is present; auto mute enabled. Condition for B/G, I and D/K standard: VCC = 5 V and f = 27 kHz (m = 54%). Condition for M standard: VCC = 5 V and f = 13.5 kHz; 6 dB gain added internally to compensate for smaller deviation. 7. R modulated and L monitored. The I2C-bus stereo adjustment has to be set to a default value. For B/G, D/K (2) and M standard the default value is 0 dB, for D/K (1) standard the default value is 0.1 dB and for D/K (3) standard the default value is 0.2 dB. 8. Using potentiometer adjustment, the AF output voltage is reduced by 1.3 dB because of the series resistor (see Fig.8). 9. Separate alignment for each standard necessary. Minimum value for D/K (3) standard is 37 dB. 10. Because the loop transfer function is not flat, the de-emphasis is superimposed by an amplitude response correction that compensates for an influence from the FM demodulators. 11. Approximate calculation of the pilot PLL loop filter can be done using the following formulae: BL(-3dB) 1.89fn 1 KO x KD f n = ------ -------------------C 2 R = --- C x K O x K D 2 with fn = natural frequency of PLL. rad Hz KO = VCO steepness -------- or 2 ------- V - V A KD = phase detector steepness -------- rad R = loop resistor. C = loop capacitor. BL(-3dB) = loop bandwidth for -3 dB. = damping factor. The formulae are only valid under the condition: 0.5 0.8 Example for BL(-3dB) = 544 Hz: C = 100 nF; R = 7.5 k; = 0.67; fn = 288 Hz. 2000 Apr 04 15 Philips Semiconductors Product specification Multistandard dual carrier stereo sound decoder TDA9873H 12. The maximum total system identification time `on' for a channel change is equal to the maximum value of tident(on) plus tI2C(read-out). The maximum total system identification time `off' for a channel change is equal to the maximum value of tident(off) plus tI2C(read-out). The fast mode is mainly for use during search tuning, program or channel select. If the channel is selected, the identification response should be switched to normal mode for improved reliability. However due to the transition from fast to normal mode, the identification bits are not valid for one integrator period. Therefore the transmitter mode detected during the fast mode must be stored before changing to the normal mode. The storage must be kept for two seconds (maximum value of tident(on) in the normal mode) from the moment of transition. The identification can now operate in the normal mode until the next tuning action. 13. Identification window is defined as total pull-in frequency range (lower plus upper side) of identification PLL (steady detection) plus window increase due to integrator (fluctuating detection). 14. Window width dependent on f. 15. The AC characteristics are in accordance with the I2C-bus specification. The maximum clock frequency is 100 kHz. Information about the I2C-bus can be found in the brochure "The I2C-bus and how to use it" (order number 9398 393 40011).

A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering is not always suitable for surface mount ICs, or for printed-circuit boards with high population densities. In these situations reflow soldering is often used. Reflow soldering Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 250 C. The top-surface temperature of the packages should preferable be kept below 230 C. 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 specifically developed. If wave soldering is used the following conditions must be observed for optimal results: TDA9873H * 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): - 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; - 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 fixed 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 is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Manual soldering Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat 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 to 5 seconds between 270 and 320 C. 2000 Apr 04 34 Philips Semiconductors Product specification Multistandard dual carrier stereo sound decoder Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE WAVE BGA, SQFP PLCC(3), SO, SOJ LQFP, QFP, TQFP SSOP, TSSOP, VSO Notes not suitable suitable(2) recommended(3)(4) recommended(5) suitable not not suitable suitable suitable suitable suitable HLQFP, HSQFP, HSOP, HTSSOP, SMS not TDA9873H REFLOW(1) 1. 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". 2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. 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. 4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. 2000 Apr 04 35 Philips Semiconductors Product specification Multistandard dual carrier stereo sound decoder DATA SHEET STATUS DATA SHEET STATUS Objective specification PRODUCT STATUS Development DEFINITIONS (1) TDA9873H This data sheet contains the design target or goal specifications for product development.
