DESCRIPTION
conformance selection for various VoIP standard environments including G.729.A (8 kbps), G.726 (32 kbps),
G.711 (64 kbps) µ-law, and A-law, and a mutual conversion function between G.729.A and G.726.
rich feature set that includes an echo canceller for 32 msec delay, DTMF detection, two tone detection functions,
and tone generation, built-in FIFOs, I/P and O/P amplifiers. This CODEC uses a single 3.3-V power supply and
has a 64-pin plastic QFP (QFP64-P-1414-0.80-BK) package.
