SAA7220 - DIGITAL FILTER FOR COMPACT DISC DIGITAL AUDIO SYSTEM

Datasheet Summary

Description

The SAA7220 is a stereo interpolating digital filter designed for the Compact Disc Digital Audio system.

For descriptive purposes, the SAA7220 is referred to as the B-chip and the SAA7210 as the A-chip.

Features

  • 16-bit serial data input (two's complement).
  • Interpolated data replaces erroneous data samples.
  • -12 dB attenuation via the active LOW attenuation input control (ATSB).
  • Smoothed transitions before and after muting.
  • Two identical finite impulse response transversal filters each with a sampling rate of four times that of the normal digital audio data.
  • Digital audio output of 32-bit words transmitted in biphase-mark code.
  • 12 S data tran.
