Configurable Multi-Channel Serial Audio Transceiver

The TDM-Pro Configurable Multi-Channel Serial Audio Transceiver Core (CWda26) is part of the AudioWorks™ family of proven audio interface cores designed to input and output digital audio streams in TDM full duplex. The TDM-Pro front-end interface also supports the well known stereo formats: I2S, Left-Justified or Right-Justified. The TDM-Pro backend interface is supplied with a choice of AMBA® or a flexible parallel interface

Specifications

• Runtime configurable audio format: multi-channel serial audio (TDM) and also I2S, Left-Justified, and Right-Justified
• Supports the hybrid TDM in I 2S format
• Full duplex operation
• Supports all commonly used sample rates including 32, 44.1, 48, 96 and 192 kHz
• Runtime configurable sample width, ranging from 8 to 32 bits per sample
• Pre-synthesis configurable sample FIFO depth
