description
The TP3056B monolithic serial interface combined PCM codec and filter device is comprised of a single-chip PCM codec (pulse code-modulated encoder and decoder) and analog filters. This device provides all the functions required to interface a full-duplex (2-wire) voice telephone circuit with a TDM (time-division-multiplexed) system. Primary applications include:
