DS2168, DS2167, (DS2167 / DS2168) ADPCM Processor
The DS2167 and DS2168 are dedicated digital signal processor (DSP) CMOS chips optimized for Adaptive Differential Pulse Code Modulation (ADPCM) based compression algorithms.
The devices halve the transmission bandwidth of “toll quality” voice from 64K to 32K bits/second and are utilized in PCM-based
