www.DataSheet4U.com Bt8110/8110B High-Capacity ADPCM Processor This specification describes the Bt8110 and Bt8110B multichannel ADPCM processor CMOS integrated circuits that implement Adaptive Differential Pulse-Code Modulation (ADPCM) encoding and decoding. The fixed-rate coding algorithms include those specified in ANSI Standard T1.303-1989. These algorithms are identical to those in ITU-T Recommendations G.726 and G.727. These circuits also implement the variable-rate or embedded codes speci.
