SPDIF Audio

SPDIF Audio



  • Conforms to the IEC 60958 International Standard
  • Programmable: supports both Receiver and Transmitter modes
  • Data mode capabilities:
    • Supports sample rates from 3kHz to 192kHz (with 98MHz SPDIF system clock)
    • 20/24 bits per sample
  • Programmable transmission rate
  • Programmable parity bit checking and generation
  • Performs master DMA handshake interfacing
  • Includes configurable internal FIFO for data streaming, with FIFO control/status signals
  • Power safe capability
  • Internal, event stimulated, interrupt request generation, with masking capability
  • Synchronization hold in the under run condition
  • Clock recovery from the SPDIF data stream
  • Detection of sample rate from the received data stream
  • Host processor interface:

    • AMBA APB slave unit to interface with the host APB controller, especially DMA
