SPDIF-Tx-Pro : Configurable SPDIF/AES3 Transmitter

Overview

The SPDIF-Tx-Pro (CWda15) is a digital audio transmitter IP core supporting the SPDIF IEC60958 and AES3 standards for PCM audio and the IEC61937 and SMPTE 337M standards for non-PCM (compressed) audio. The core is very configurable allowing many features of the standards to be optionally supported by hardware or software. The structure of the CWda15 allows enhanced functionalities for specific applications by using the optional Add-on-Modules (AOM).

Key Features

  • Supports the IEC60958 (SPDIF) and AES3 standards for PCM audio transmission
  • Supports the IEC61937, SMPTE 337M standards for non-PCM audio transmission
  • Automatic insertion of Validity bits in non-PCM mode
  • Supports any sample rate Fs by setting the audio clock frequency to 256*Fs including 32, 44.1, 48, 96 and 192 kHz
  • Configurable audio data FIFO reporting the number of samples in FIFO and programmable almost empty condition
  • Channel Status and User Data memory mapped buffers
  • Separate interfaces for data and control
  • Supports up to 24 bits per sample

Benefits

  • Reduced backend bus bandwidth by automatic insertion of stuffing bits in non-PCM mode
  • Modular Structure using optional Add-on-Modules (AOM)
  • Permits rapid implementation of a configurable audio transmitter for SPDIF and all its variations
  • 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
