VIF-PLL demodulator and FM-PLL detector
Preliminary specification
TDA9800
FEATURES
Suitable for negative vision modulation
Applicable for IF frequencies of 38.9 MHz, 45.75 MHz
and 58.75 MHz
Gain controlled wide band VIF amplifier (AC coupled)
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
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
Alignment-free FM-PLL detector with high linearity
Stabilizer circuit for ripple rejection and to achieve
constant output signals
5 to 8 V positive supply voltage range, low power
consumption (300 mW at +5 V supply voltage).
GENERAL DESCRIPTION
The TDA9800 is a monolithic integrated circuit for vision
and sound IF signal processing in TV and VTR sets.
