Preliminary specification
Multistandard VIF-PLL and
FM-PLL/AM demodulator
TDA9812
FEATURES
5 V positive supply voltage
Gain controlled wide band VIF-amplifier (AC-coupled)
True synchronous demodulation with active carrier
regeneration (very linear demodulation, good
intermodulation figures, reduced harmonics, excellent
pulse response)
Gated phase detector for L/L accent standard
VCO frequency switchable between L and L accent
(alignment external) picture carrier frequency
Separate video amplifier for sound trap buffering with
high video bandwidth
VIF AGC detector for gain control, operating as peak
sync detector for B/G (optional external AGC) and peak
white detector for L; signal controlled reaction time for L
Tuner AGC with adjustable Take Over Point (TOP)
AFC detector without extra reference circuit
AC-coupled limiter amplifier for sound intercarrier signal
Alignment-free FM-PLL demodulator with high linearity,
switchable de-emphasis for FM
AM-SIF AGC detector for gain controlled SIF amplifier
AM demodulator without extra reference circuit
Stabilizer circuit for ripple rejection and to achieve
constant output signals.
GENERAL DESCRIPTION
The TDA9812/T is an integrated circuit for multistandard
vision IF signal processing and AM and FM sound
demodulation in TV and VTR sets.
