Single standard VIF-PLL with QSS-IF and

FM-PLL demodulator

Product specification

TDA9808

FEATURES

• 5 V supply voltage (9 V supply voltage for TDA9808

(DIP20) only)

• Applicable for IFs (Intermediate Frequencies) of

38.9 MHz, 45.75 MHz and 58.75 MHz

• Gain controlled wide band 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 Phase Locked Loop (PLL)-bandwidth control at

negative modulated standards

• VIF Automatic Gain Control (AGC) detector for gain

control, operating as peak sync detector

• Tuner AGC with adjustable TakeOver Point (TOP)

• Automatic Frequency Control (AFC) detector without

extra reference circuit

• AC-coupled limiter amplifier for sound intercarrier signal

• Alignment-free FM-PLL demodulator with high linearity

• Sound IF (SIF) input for single reference Quasi Split

Sound (QSS) mode (PLL controlled); SIF AGC detector

for gain controlled SIF amplifier; single reference QSS

mixer for high performance

• Electrostatic Discharge (ESD) protection for all pins.

GENERAL DESCRIPTION

The TDA9808 is an integrated circuit for single standard

(negative modulated) vision IF signal processing and FM

demodulation, with single reference QSS-IF in TV and

VTR sets.
