MT9125 Dual ADPCM Transcoder

The Dual-channel ADPCM transcoder is a low power, CMOS device capable of two encoder functions and two decoder functions. Two 64 kbit/s PCM channels are compressed into two 32 kbit/s ADPCM channels, and two 32 kbit/s ADPCM channels are expanded into two 64 kbit/s PCM channels. The 32 kbit/s ADPCM t.
