The DN9652 dual network bridge has been designed to allow two dissimilar digital audio networks to interface simply and reliably. There are many different multichannel digital audio protocols available today. Some are well established and have been in common use for several years, others have appeared recently, and all are vying for recognition and market share. Interfacing different protocols can be difficult and expensive, often requiring the use of inflexible, proprietary hardware. Connecting different audio networks together, which often have differing sample rates and clock domains can be a difficult and expensive process.

Currently available interfaces include:

  • Audinate Dante
  • Aviom A-Net
  • Cirrus Logic CobraNet
  • Digigram EtherSound
  • MADI (AES10)

The DN9652 Dual Network Bridge supports network modules designed and manufactured by Cirrus Logic, Inc., Lab X Technologies, LLC, and Audinate Pty Ltd.

Clock Synchronisation

The DN9652 clock synchronisation scheme is divided into two domains (A & B) for each of the two network module interfaces.

Each Network Clock Domain may select from:

  • External Network Clock
  • External Network Clock with Word Clock In Synchronisation
  • DN9652 Onboard Oscillator
  • Network Module Onboard Clock
  • Clock selection from other Network Module
  • Word Clock In
  • Video Black Burst In

Features and Specifications:

  • Two network interfaces each supporting up to 64 bidirectional channels at up to 24-bit 96 kHz audio
  • 1:1 channel mapping between Network Module interfaces
  • Bidirectional Asynchronous Sample Rate Conversion (ASRC) on every channel with Bypass facilit
  • User-selectable bidirectional Stop Output Clock facility if Input Clock fails function, to propagate network failures across ASRC for automatic or manual redundancy switchover
  • Data format word length truncation and dithering
  • Ultra-high stability reference-grade 1 part-per-million (1 ppm) temperature-controlled clock oscillator
  • Supports operation at 44.1 kHz, 48 kHz and 96 kHz sampling frequencies
  • Flexible third party interface clock synchronisation options:-
    Network Module Incoming and Outgoing Clocks
    Word Clock Input
    Word Clock Output
    Video Black Burst In (PAL/SECAM/NTSC formats in Standard Definition (SD) and High Definition (HD) resolutions)
  • Platform-independent web browser configuration interface software hosted on integrated Linux web server
  • Ethernet Control port for remote computer connection (web browser configuration and software updating)
  • 100V-240V universal power supply
  • 1U High 19” rackmount
