TDA9808 Datasheet

Single Standard Vif-pll With Qss-if And Fm-pll Demodulator

Manufacturer: NXP Semiconductors

TDA9808 Overview

plastic dual in-line package; 20 leads (300 mil) plastic small outline package; body width 7.5 mm GENERAL DESCRIPTION TDA9808 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.

TDA9808 Key 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,
  • Robustness for over-modulation better than 105% due to Phase Locked Loop (PLL)-bandwidth control at negative modulated s
  • 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
