AT2008 8 Channels ADPCM Processor Atelic Systems, Inc. AT2008 Application Note Preliminary 8 Channels ADPCM Processor Version 1.0 January 29, 2001 Description The AT2008 is an eight full-duplex channels ADPCM processor. It follows the G.726 ITU Standard for ADPCM compression for 40k, 32k, 24k and 16k bit rates with selectable µ-law and A-law input/output. This chip can operate on 16 channels of PCM to ADPCM compression, 16 channels of ADPCM to PCM decompression, 8 channels of full-duplex operation in an 8KHz frame basis, or any combination of M-channels of compression plus N-channels of decompression when M+N
