TDA9816M
FEATURES
5 V supply voltage
Gain controlled wideband Video IF (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 and PLL
bandwidth control for negative modulation standards
VCO (Voltage Controlled Oscillator) frequency can be
switched between L and L accent (alignment external)
picture carrier frequency
VIF AGC (Automatic Gain Control) detector for gain
control, operating as peak sync detector for B/G and
peak white detector for L; signal controlled reaction time
for L
Tuner AGC with adjustable TakeOver Point (TOP)
AFC (Automatic Frequency Control) detector without
extra reference circuit
AC-coupled limiting amplifier for sound intercarrier
signal
Alignment-free FM PLL (Phase-Locked Loop)
demodulator with high linearity; integrated de-emphasis
resistor
Integrated level detector
Alignment-free FM radio AFC detector with external
resonator
RIF (Radio IF) amplifier for 10.7 MHz
SIF (Sound IF) input for single reference QSS (Quasi
Split Sound) 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 (Electrostatic Discharge) protection for all pins.
GENERAL DESCRIPTION
The TDA9816M is an integrated circuit for multistandard
vision IF signal processing, sound AM and FM
demodulation and FM radio demodulation in multimedia
sets.
