The DEM-DAI demonstration board provides a standard platform for evaluating Burr-Brown digital audio products including stereo DAC, ADC and CODEC devices. The DEM-DAI board includes a digital audio receiver and transmitter, along with their associated support circuitry. The receiver and transmitter accept and output S/PDIF digital audio streams via RCA and optical connections. The DEM-DAI board also includes an on-board crystal oscillator/divider circuit for generating the required audio clocks independent of the digital audio receiver.

In addition to the digital audio interface and timing circuits, there are connectors for DEM-PCM demo boards, power supplies, and stereo audio inputs and outputs. On-board switches and jumpers are used to configure the DEM-DAI board for use with a variety of DEM-PCM demo boards. An on-board DAC post filter circuit is also included and is located near the stereo audio output connectors. This board is used in conjunction with al DEM-PCM boards.

Features

  • Digital audio receiver and transmitter supports S/PDIF digital audio interface (both RCA coaxial cable and optical connections)
  • Programmable system clock source: Digital Audio Receiver or Crystal Oscillator
  • Programmable system clock rate: 256fs, 384fs, or 512fs
  • Normal or inverted system clock input for digital audio transmitter
  • Master or slave mode operation
  • Receiver and transmitter mode selection via toggle switches
  • Dip switch for setting digital transmitter flags
  • Header connections accept DEM-PCM demo boards
  • RCA jacks for stereo audio inputs and outputs
  • On-board stereo DAC post filter
  • Power supply connector for digital and analog power supplies
  • Operates from a single +5V supply for the digital audio interface section
  • DAC post filter operates from +/-5V to +/-15V
