open-in-new Find other Audio CODECs


The TLV320AIC1106 PCM codec is designed to perform transmit encoding analog-to-digital (A/D) conversion, receive decoding digital-to-analog (D/A) conversion, and transmit and receive filtering for voice-band communications systems. The TLV320AIC1106 device operates in either the 13-bit linear or 8-bit companded (u-law) mode. The PCM codec generates its own internal clocks from a 2.048-MHz master clock input.
