MT9126 Datasheet (MITEL) - Quad ADPCM Transcoder

MT9126, Quad ADPCM Transcoder

The Quad ADPCM Transcoder is a low power, CMOS device capable of four encode and four decode functions per frame.

Four 64 kbit/s PCM octets are compressed into four 32, 24 or 16 kbit/s ADPCM words, and four 32, 24 or 16 kbit/s ADPCM words are expanded into four 64 kbit/s PCM octets.

The 32, 24 and
