IDT821034 - QUAD PCM CODEC

General Description

The IDT821034 is a single-chip, four channel PCM CODEC with onchip filters and programmable gain setting.

This device provides both µ-Law and A-Law companding digital-to-analog and analog-to-digital conversions based on ITU-T G.711 - G.714 specifications.

Key Features

  • 4 channelCODEC with on-chip digital filters.
  • Software Selectable A-law/µ-law companding.
  • Programmablegainsetting.
  • Automatic master clock frequency selection: 2.048MHz, 4.096 MHz or 8.192MHz.
  • Flexible PCM interface with up to 128 programmable time slots, data rate from 512 kbits/s to 8.192 Mbits/s.
  • 5 SLIC signaling pins per channel.
  • Flexible Serial Control Interface to microcontroller.
  • Software programmable timing modes.
