Description

QSOP Pin # 1 TQFP Pin # 43 Name ENA1 Description Data Sheet SSI Enable Strobe/ST-BUS & GCI Mode for Rin/Sout (Input).This pin has dual functions depending on whether SSI or ST-BUS/GCI is selected.For SSI, this strobe must be present for frame synchronization.This is an active high channel enable strobe, 8 or 16 data bits wide, enabling serial PCM data transfer for on Rin/Sout pins.Strobe period is 125 microseconds.For ST-BUS or GCI, this pin, in conjunction with the MD1 pin, selects the p

Features

Contains two echo cancellers: 112 ms acoustic echo canceller Works with low cost voice codec. ITU-T G.711 or signed mag µ/A-Law, or linear 2’s comp Each port may operate in different format Advanced NLP design - full duplex speech with no switched loss on audio paths Fast re-convergence time: tracks changing echo environment quickly Adaptation algorithm converges even during Double-Talk.
