TDM-Pro : Configurable Multi-Channel Serial Audio Transceiver

Overview

Key Features

• Runtime configurable audio format: multi-channel serial audio (TDM) and also I2S, Left Justified, and Right Justified stereo formats
• Supports the hybrid TDM in I2S 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
• Reports FIFO full and empty conditions and the number of samples in both RX and TX FIFOs
• Runtime configurable RX Upper-FIFO-Limit; a request is activated when this limit is exceeded
• Runtime configurable TX Lower-FIFO-Limit; a request is activated when this limit is exceeded
• Supports slave or master modes of the audio bus
• Supports up to 128 audio channels

Benefits

• Permits rapid development of a TDM audio front-end interface for a multitude of vendor specific formats
• Flexible backend interface: AMBA®, CoreConnect™ or just parallel with REQ/ACK handshaking

Deliverables

• Verilog source code or FPGA netlist
• Verilog testbench for RTL simulation
• Synthesis constraints
• Datasheet
• Example software driver
