Product specification
Multistandard vision and sound-IF PLL with
DVB-IF processing
TDA9819
FEATURES
5 V supply voltage
Applicable for IF frequencies of 38.9 MHz and
45.75 MHz
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 and
excellent pulse response)
VCO frequency switchable between TV (M or BG/L)
IF-picture carrier and Digital Video Broadcast (DVB)
frequency
Separate video amplifier for sound trap buffering with
high video bandwidth
VIF AGC detector for gain control, operating as peak
sync detector for M and B/G and peak white detector for
L; 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
AC-coupled limiter amplifier for sound intercarrier signal
Alignment-free FM-PLL demodulator with high linearity
AM demodulator without extra reference circuit
Stabilizer circuit for ripple rejection and to achieve
constant output signals.
DVB functions
Gain controlled IF-amplifier
Mixer for DVB-IF
VCO for QAM carrier recovery
External VCO control for DVB
Internal and external AGC for DVB
DVB output level adjust via AGC adjust
High level DVB operational output amplifier.
GENERAL DESCRIPTION
The TDA9819 is an integrated circuit for multistandard
