I2S/Left-Justified/TDM Digital Audio Interface

Overview

The AR38U12 is a soft macro IP supporting industry-standard I2S, Left-Justified and Time-Division-Multiplexed (TDM) serial interface to parallel PCM (pulse-code-modulation) data format conversion for digital voice/audio data communication.

The IP is highly flexible with enriched programmable features that allow users to define the IP settings for their unique applications. The IP transfers and receives serial data in master or slave modes for both transmitter (TX) and receiver (RX).

The IP is portable to any logic process node for silicon realization. It is now silicon-proven in UMC55nm logic processes.
