november 1992 5 philips semiconductors preliminary speci?cation multistandard vif-pll demodulator TDA9803 functional description vision if input the vision if amplifier consists of three ac-coupled differential amplifier stages; each stage comprises a controlled feedback network by means of emitter degeneration. if and tuner agc the automatic control voltage to maintain the video output signal at a constant level is generated according to the transmission standard. for negative modulation the peak-sync level is detected, for positive modulation the peak white level is detected. the agc detector charges and discharges the capacitor on pin 19 to set the if gain and the tuner gain. the standard is switched by the voltage on pin 8. to reduce the response time for positive modulation (which needs a very long time constant) a black level detector (c bl ) increases the agc capacitor discharge current for low-level video signals. the agc capacitor voltage is transferred to an internal if control signal, and is fed to the tuner agc to generate the tuner agc output current on pin 12 (open-collector output). the tuner agc voltage take over point is adjusted on pin 3. this allows the tuner and the if saw filter to be matched to achieve the optimum if input level. frequency detector, phase detector and video demodulator the if amplifier output signal is fed to a frequency detector and to a phase detector. the frequency detector is operational before lock-in. a dc current is generated which is proportional to the frequency difference between the input frequency and the vco frequency. after lock-in, the frequency detector and the phase detector generate a dc current proportional to the phase difference between vco and input signals. the control signal for the vco is provided by the phase detector. the video demodulator is a linear multiplier, designed for low distortion and wide bandwidth. the vision if input signal is multiplied by the in-phase component of the vco output. the demodulated output signal is fed via an integrated low-pass filter (f g = 12 mhz) to the video amplifier for suppression of the carrier harmonics. the polarity of the video signal is switched in the demodulator stage according to the tv standard. vco and travelling wave divider the vco operates with a symmetrically-connected reference lc-circuit, operating at double vision carrier frequency. frequency control is performed by an internal varicap diode. the voltage to set the vco frequency to the actual frequency of double vision carrier frequency, is also amplified and converted for the afc output current. the vco signal is divided-by-two in a travelling wave divider, which generates two differential output signals with 90 degree phase difference independent of frequency. video ampli?er, buffer and noise clipping the video amplifier is a wide bandwidth operational amplifier with internal feedback. dependent on transmission standard, a level shifter provides the same sync level for positive as for negative modulation. a nominal positive modulated video signal of 1 v (p-p) is present on the composite video output (pin 13). the input impedance of the 7 db wideband buffer amplifier (with internal feedback) is suitable for ceramic sound trap filters. the cvbs output (pin 7) provides a positive video signal of 2 v (p-p). noise clipping is provided internally. www.datasheet.co.kr datasheet pdf - http://www..net/

november 1992 20 philips semiconductors preliminary speci?cation multistandard vif-pll demodulator TDA9803 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. www.datasheet.co.kr datasheet pdf - http://www..net/
