The output audio formats supported by the device include 2 AES/EBU and I S, and two other industry standard serial Description digital formats. A variety of audio processing features are The GS2970 is a multi-rate SDI Receiver which includes provided to ease implementation. Audio clocks are complete SMPTE processing, as per SMPTE 425M, 292 and internally generated and provided by the device. SMPTE 259M-C. The SMPTE processing features can be bypassed to support signals with other coding schemes. The device features an Integrated Reclocker with an internal VCO and a wide Input Jitter Tolerance (IJT) of 0.7UI. A serial digital loop-through output is provided, which can be configured to output either reclocked or non-reclocked serial digital data. The serial digital output can be connected to an external cable driver. GS2970 3Gb/s, HD, SD SDI Receiver Complete with 2 of 145 SMPTE Audio and Video Processing Data Sheet 47478 - 4 September 2012
