Product speciﬁcation

Multistandard VIF-PLL with QSS-IF and

AM demodulator

TDA9810

FEATURES

• 5 V supply voltage

• Gain controlled wide band Video Intermediate

Frequency (VIF)-amplifier (AC-coupled)

• True synchronous demodulation with active carrier

regeneration (very linear demodulation, good

intermodulation figures, reduced harmonics, excellent

pulse response)

• Gated phase detector for L/L accent standard;

robustness for over-modulation until 105%

• Voltage Controlled Oscillator (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 Automatic Gain Control (AGC) detector for gain

control, operating as peak sync detector for B/G

(optional external AGC) and peak white detector for L;

signal controlled reaction time for L

• Tuner AGC with adjustable TakeOver Point (TOP)

• AFC detector without extra reference circuit

• SIF-input for single reference Quasi Split Sound (QSS)

mode (Phase Locked Loop (PLL) controlled); Sound

Intermediate Frequency (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.

GENERAL DESCRIPTION

The TDA9810 is an integrated circuit for multistandard

vision IF signal processing and sound AM demodulation,

with single reference QSS-IF in TV and VCR sets.
