Multistandard/MAC VIF-PLL with QSS-IF
and dual FM-PLL/AM demodulator
Product specification
TDA9815
FEATURES
5 V supply voltage
Two switched VIF inputs, 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)
Robustness for over-modulation better than 105% due
to gated phase detector at 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, peak white detector for L and
peak level for MAC (optional external AGC);
signal controlled reaction time for L and MAC
Tuner AGC with adjustable takeover point (TOP)
AFC detector without extra reference circuit
AC-coupled limiter amplifier for sound intercarrier signal
with input switch for additional FM signal
Two alignment-free FM-PLL demodulators with
high linearity
SIF input for single reference QSS mode (PLL
controlled); SIF AGC detector for gain controlled SIF
amplifier; single reference QSS mixer able to operate in
high performance single reference QSS mode
AM demodulator without extra reference circuit
Stabilizer circuit for ripple rejection and to achieve
constant output signals
ESD protection for all pins.
GENERAL DESCRIPTION
The TDA9815 is an integrated circuit for multistandard
vision IF signal processing (inclusive MAC) and sound AM
and dual FM demodulation, with single reference QSS-IF
in TV and VCR sets.
