TDA9880 Datasheet Alignment-free Multistandard Vision And Fm Sound If-pll Demodulator

Manufacturer: NXP Semiconductors

TDA9880 Overview

plastic shrink dual in-line package; 20 leads (300 mil) plastic small outline package; GENERAL DESCRIPTION The TDA9880(T) is an integrated circuit for multistandard vision IF signal processing and FM demodulation in TV and VTR sets.

TDA9880 Key Features

  • 5 V supply voltage
  • Gain controlled wide-band Vision Intermediate Frequency (VIF) amplifier (AC-coupled)
  • True synchronous demodulation with active carrier regeneration (very linear demodulation, good intermodulation figures,
  • Fully integrated VIF Voltage Controlled Oscillator (VCO), alignment-free
  • Digital acquisition help, VIF frequencies of 38.0, 38.9, 45.75 and 58.75 MHz
  • 4 MHz reference frequency input [signal from Phase-Locked Loop (PLL) tuning system] or operating as crystal oscillator
  • VIF Automatic Gain Control (AGC) detector for gain control, operating as peak sync detector, fast reaction time ORDERING
  • Precise fully digital Automatic Frequency Control (AFC) detector with 4-bit digital-to-analog converter
  • Fully integrated sound carrier trap for 4.5, 5.5, 6.0 and 6.5 MHz, controlled by reference signal
  • Alignment-free selective FM-PLL demodulator with high linearity and low noise
