HI3DE-400/12
This module serves as a standard multi rate SDI input card, with the added features of 12 separate audio disembedder modules and a TDM multiplexor that feeds all of the disembedded audio to a central crosspoint. The video circuitry supports SDI video signals from 270 Mb/Sec to 2.97 Gb/Sec, SMPTE 259, 292 and 424 standards. The disembedder circuitry supports 16 channels of audio, or 4 audio groups for SMPTE 292 and 424 standards, and 8 channels of audio, or 2 audio groups, for SMPTE 259 standards. Each disembedder channel is fully isolated from the others, so different video standards can be presented to a single card in any combination required. Each channel derives its necessary clocks from the incoming video stream. The overriding concern with a TDM audio system such as the Utah 400 ESP system is that the audio MUST be 48 KHz sample rate, and it MUST be synchronous with the AES reference presented to the router. Asynchronous audio signals will not pass through the system correctly.
