Product Detail

The Quad ADPCM Transcoder is a low power, CMOS device capable of four encode and four decode functions per frame. Four 64 kbps PCM octets are compressed into four 32, 24 or 16 kbps ADPCM words, and four 32, 24 or 16 kbps ADPCM words are expanded into four 64 kbps PCM octets. The 32, 24 and 16 kbps ADPCM transcoding algorithms utilized conform to ITU-T Recommendation G.726 (excluding 40 kbps), and ANSI T1.303 - 1989. Switching, on-the-fly, between 32 kbps and 24 kbps ADPCM, is possible by controlling the appropriate mode select (MS1 - MS6) control pins. All optional functions of the device are pin selectable allowing a simple interface to industry standard codecs, digital phone devices and Layer 1 transceivers. Linear coded PCM is provided to facilitate external DSP functions
