The RAVENNA COMi.MX from ALC NetworX is a fully self-contained 2x 64 channel RAVENNA SoM board. It is offered to manufacturers for easy integration of RAVENNA/AES67 functionality into their existing product designs.
Its performance capabilities are aligned with the highest demands in network throughput, channel count and latency. Full AES/EBU bit transparency and support for sample rates up to 192kHz render it extremely useful for broadcast and recording applications. It offers maximum flexibility in IP stream configuration and processing to work under any application environment from simple AES/EBU stereo streaming to high-performance MADI-over-IP transfer and beyond. A jitter buffer size of up to 80 ms per channel can accommodate large packet jitter as may be seen in certain WAN applications.
Two RAVENNA Gigabit Ethernet interfaces offer the choice of full streaming redundancy or doubling the available network bandwidth. Connectivity to the host platform is provided by two independent audio interfaces: 64-channel TDM and 64-channel MADI. An integrated fully switchable 4-tier 256x256 channel audio matrix adds maximum signal routing flexibility.
Finally, the module can serve as a PTP grandmaster in applications where an external grandmaster is not available. Its built-in GenLock capability offers a wide range of external synchronization options. The board fully supports AES67 interoperability.
The RAVENNA COMi.MX module is designed to serve a wide range of applications, e.g. I/O module for mixing desks or stage box interfaces, high-capacity signal conversion / processing units,
interface for high-performance audio “end” points (i.e. analog / digital audio signal converters / congregators, speaker arrays et al).
It is exclusively available for OEM integration to RAVENNA partner companies.
