MSM7560L - Single Rail ADPCM CODEC

Description

The MSM7540L/7560L are single channel ADPCM CODEC ICs which perform mutual transcoding between an analog voice band signal 300 to 3400 Hz and 32 kbps ADPCM serial data.

Using advanced circuit technology, these devices operate from a single 3 V power supply and provide low power consumption.

Features

  • Single 3 V Power Supply Operation.
  • ADPCM Algorithm : Complies completely with 1988's version ITU-T G.721 (32 kbps).
  • Transmit/Receive Full-Duplex Operation.
  • Transmit/Receive Synchronous Mode Only.
  • Serial ADPCM Transmission Data Rate : 32 kbps to 2048 kbps.
  • Serial PCM Transmission Data Rate : 64 kbps to 2048 kbps.
  • PCM Interface Coding Format MSM7540L : A-law or Linear (14 bit, 2's compliment) Selectable MSM7560L : m-law or Linear (14.
