1998 may 11 7 philips semiconductors product speci?cation 8-bit microcontroller with dtmf generator PCD3349A 6.2 frequency registers the two frequency registers hgf and lgf define two frequencies. from these, the digital sine synthesizers together with the digital-to-analog converters (dacs) construct two sine waves. their amplitudes are precisely scaled according to the bandgap voltage reference. this ensures tone output levels independent of supply voltage and temperature. the amplitude of the low group frequency sine wave is attenuated by 2 db compared to the amplitude of the high group frequency sine wave. the two sine waves are summed and then filtered by an on-chip switched capacitor and rc low-pass filters. these guarantee that all dtmf tones generated fulfil the cept recommendations with respect to amplitude, frequency deviation, total harmonic distortion and suppression of unwanted frequency components. the value 00h in a frequency register stops the corresponding digital sine synthesizer. if both frequency registers contain 00h, the whole frequency generator is shut off, resulting in lower power consumption. the frequency of the sine wave generated is dependent upon the decimal value x held in the frequency registers (hgf and lgf), and this may be calculated as follows: ; where 60 x 255. the frequency limitation given by x 3 60 is due to the low-pass filters which would attenuate higher frequency sine waves. 6.3 dtmf frequencies assuming an oscillator frequency f xtal = 3.58 mhz, the dtmf standard frequencies can be implemented as shown in table 3. the relationship between telephone keyboard symbols and the frequency register contents are given in table 4. f f xtal 23 x 2 + () [] -------------------------------- - = table 3 dtmf standard frequencies and their implementation; value = lgf, hgf contents table 4 dialling symbols, corresponding dtmf frequency pairs and frequency registers content value (hex) frequency (hz) deviation standard generated (%) (hz) dd 697 697.90 0.13 0.90 c8 770 770.46 0.06 0.46 b5 852 850.45 - 0.18 - 1.55 a3 941 943.23 0.24 2.23 7f 1209 1206.45 - 0.21 - 2.55 72 1336 1341.66 0.42 5.66 67 1477 1482.21 0.35 5.21 5d 1633 1638.24 0.32 5.24 telephone keyboard symbols dtmf freq. pairs (hz) lgf value (hex) hgf value (hex) 0 (941, 1336) a3 72 1 (697, 1209) dd 7f 2 (697, 1336) dd 72 3 (697, 1477) dd 67 4 (770, 1209) c8 7f 5 (770, 1336) c8 72 6 (770, 1477) c8 67 7 (852, 1209) b5 7f 8 (852, 1336) b5 72 9 (852, 1477) b5 67 a (697, 1633) dd 5d b (770, 1633) c8 5d c (852, 1633) b5 5d d (941, 1633) a3 5d (941, 1209) a3 7f # (941, 1477) a3 67

1998 may 11 18 philips semiconductors product speci?cation 8-bit microcontroller with dtmf generator PCD3349A 18 soldering 18.1 introduction there is no soldering method that is ideal for all ic packages. wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. however, wave soldering is not always suitable for surface mounted ics, or for printed-circuits with high population densities. in these situations reflow soldering is often used. this text gives a very brief insight to a complex technology. a more in-depth account of soldering ics can be found in our data handbook ic26; integrated circuit packages (order code 9398 652 90011). 18.2 dip 18.2.1 s oldering by dipping or by wave the maximum permissible temperature of the solder is 260 c; solder at this temperature must not be in contact with the joint for more than 5 seconds. the total contact time of successive solder waves must not exceed 5 seconds. the device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (t stg max ). if the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. 18.2.2 r epairing soldered joints apply a low voltage soldering iron (less than 24 v) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. if the temperature of the soldering iron bit is less than 300 c it may remain in contact for up to 10 seconds. if the bit temperature is between 300 and 400 c, contact may be up to 5 seconds. 18.3 so 18.3.1 r eflow soldering reflow soldering techniques are suitable for all so packages. 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 techniques exist for reflowing; for example, thermal conduction by heated belt. dwell times vary between 50 and 300 seconds depending on heating method. typical reflow temperatures range from 215 to 250 c. preheating is necessary to dry the paste and evaporate the binding agent. preheating duration: 45 minutes at 45 c. 18.3.2 w ave soldering wave soldering techniques can be used for all so packages if the following conditions are observed: a double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. the longitudinal axis of the package footprint must be parallel to the solder flow. the package footprint must incorporate solder thieves at the downstream end. 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. maximum permissible solder temperature is 260 c, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 c within 6 seconds. 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. 18.3.3 r epairing soldered joints fix the component by first soldering two diagonally- opposite end leads. use only a low voltage soldering iron (less than 24 v) 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.
