Description  
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 16 kbit/s ADPCM transcoding algorithms utilized  
conform to ITU-T Recommendation G.726 (excluding  
40 kbit/s), and ANSI T1.303 - 1989.  
Pin selectable ITU-T or signed magnitude PCM  
coding  
Single 5 volt power supply  
Switching, on-the-fly, between 32 kbit/s and 24 kbit/s  
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.
