TDM-Rx-Pro: Configurable Multi-channel Serial Audio Receiver

Overview

Key Features

• Runtime configurable input format: multi-channel serial audio (TDM), or stereo I2S, Left Justified or Right Justified
• Supports all commonly used sample rates including 32, 44.1, 48, 96, 192 and 384 kHz
• Runtime configurable sample width, ranging from 8 to 32 bits per sample
• Pre-synthesis configurable sample FIFO depth
• Reports FIFO empty condition
• Reports number of samples in FIFO
• Runtime configurable Upper-FIFO-Limit; a request signal is activated when this limit is exceeded
• Supports up to 128 audio channels
• Supports slave or master modes of the audio bus
• Supports TDM audio formats from multiple vendors

Benefits

• Permits rapid development of a TDM audio 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
