The PCM3500EG4 is a mono SoundPlus? Voice/Modem Codec designed for modem analog front end (AFE) and speech processing applications. The PCM3500's low power operation from 2.7 to 3.6V power supplies, along with an integrated power-down mode, makes it ideal for portable applications. The PCM3500 integrates all of the functions needed for a modem or voice codec, including delta-sigma digital-to-analog and analog-to-digital converters, input anti-aliasing filter, digital high-pass filter for DC blocking and an output low-pass filter. The synchronous serial interface provides for a simple, or glue-free interface to popular DSP and RISC processors. The serial interface also supports Time Division Multiplexing (TDM), allowing up to four CODECs to share a single 4-wire serial bus.
