FEATURES
GENERAL DESCRIPTION
·
5 V supply voltage
The TDA9811 is an integrated circuit for multistandard
vision IF signal processing and sound AM, with single
reference QSS-IF in TV and VCR sets.
·
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 and peak white detector for L
(optional external AGC); signal controlled reaction time
for L
·
Tuner AGC with adjustable takeover point (TOP)
AFC detector without extra reference circuit
·
·
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
·
AM mute (especially for NICAM)
·
Stabilizer circuit for ripple rejection and to achieve
constant output signals
·
ESD protection for all pins.
