Description

The TWL1109 voice-band audio processor (VBAP) is designed to perform the transmit encoding analog/digital (A/D) conversion and receive decoding digital/analog (D/A) conversion, together with transmit and receive filtering,for voice-band communications systems. The TWL1109 device operates in either the 15-bit linear or 8-bit companded (-law or A-Law) mode, which is selectable through the I2C interface. From a 2.048-MHz master clock input,the VBAP generates its own internal clocks.
