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 telephony networks. 022698 1/15 DS2167/DS2168 PRODUCT OV.

• Speech compression chip compatible with standard
ADPCM algorithms:
– DS2167 supports “new” T1Y1 recommendations (July 1986) and “new” CCITT G.721 recommendations
– DS2168 supports “old” CCITT G.721 recommendations
• Dual independent channel architecture
– device may
be programmed to perform full duplex, 2-channel expansions, or 2-channel compressions
• Interconnects directly with µ-law or A-law codec/filter
