may 1994 5 philips semiconductors product speci?cation if ampli?er/demodulator for fm radio receivers tda1599 functional description the limiter amplifier has five stages of if amplification using balanced differential limiter amplifiers with emitter follower coupling. decoupling of the stages from the supply voltage line and an internal high-ohmic dc feedback loop give a very stable if performance. the amplifier gain is virtually independent of changes in temperature. the fm demodulator is fully balanced and compromises two cross-coupled differential amplifiers. the quadrature detection of the fm signal is performed by direct feeding of one differential amplifier from the limiter amplifier output, and the other via an external 90 degrees phase shifting network. the demodulator has a good stability and a small zero-cross-over shift. the bandwidth on the demodulator output is restricted by an internal low-pass filter to approximately 1 mhz. non-linearities, which are introduced by demodulation, are compensated by the thd compensation circuit. for this reason, the demodulator resonance circuit (between pins 10 and 11) must have a loaded q-factor of 19. consequently, there is no need for the demodulator tuned circuit to be adjusted for minimum distortion. adjustment criterion is a symmetrical stop pulse. the control voltage for the mute attenuator (pin 16) is derived from the values of the level detector and the detuning detector output signals. the mute attenuator has a fast attack and a slow decay determined by the capacitor on pin 16. the af signal is fed via the mute attenuator to the output (pin 4). a weighted control voltage (pin 6) is obtained from the mute attenuator control voltage via a buffer amplifier that introduces an additional voltage shift and gain. the level detector generates a voltage output signal proportional to the amplitude of the input signal. the unweighted level detector output signal is available in fm-mute-on condition (mode switch). the open-collector tuning stop output voltages stop-0 and stop-1 (pins 15 and 14) are derived from the detuning and the input signal level. the pins 14 and 15 may be tied together, if only one tuning-stop output is required.

may 1994 21 philips semiconductors product speci?cation if ampli?er/demodulator for fm radio receivers tda1599 soldering 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 ic package databook (order code 9398 652 90011). dip 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. 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. so 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. 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. 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.
