Preliminary specication
Multistandard VIF-PLL demodulator
TDA9803
FEATURES
Suitable for negative and positive vision modulation
Gain controlled 3-stage IF amplifier; suitable for VIF
frequencies up to 60 MHz
True synchronous demodulation with active carrier
regeneration (ultra-linear demodulation, good
intermodulation figures reduced harmonics and
excellent pulse response)
Peak sync AGC for negative modulation, e.g. B/G
standard
Peak white AGC for positive modulation, e.g. L standard
Video amplifier to match sound trap and sound filter
AGC output voltage for tuner; adjustable take-over point
(TOP)
AFC detector without extra reference circuit
Stabilizer circuit for ripple rejection and to achieve
constant output signals
5 to 8 V positive supply voltage range, low power
consumption (230 mW at
+5 V supply)
GENERAL DESCRIPTION
The TDA9803 is a monolithic integrated circuit for vision IF
signal processing in multistandard TV and VTR sets.
