Philips Electronics 

Philips Semiconductors

VIF-PLL with QSS-IF and

dual FM-PLL demodulator

Product specification

TDA9813T

FEATURES

• 5 V supply voltage

• 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)

• Separate video amplifier for sound trap buffering with

high video bandwidth

• VIF-AGC detector for gain control, operating as peak

sync detector

• Tuner AGC with adjustable takeover point (TOP)

• AFC detector without extra reference circuit

• AC-coupled limiter amplifier for sound intercarrier signal

• Two alignment-free FM-PLL demodulators with

high linearity

• 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

• Stabilizer circuit for ripple rejection and to achieve

constant output signals

• ESD protection for all pins.

GENERAL DESCRIPTION

The TDA9813T is an integrated circuit for vision IF signal

processing and sound dual FM demodulation, with single

reference QSS-IF in TV and VCR sets. For negative

modulation standards only.
