Product Details

Description



Features:

5V 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,
excellentpulse response)
Robustness for over-modulation better than 105% due
to gated phase detector at L/Laccent standard
VCOfrequency switchable between Land 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 highlinearity
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.
