Description The GS2970A is a multi-rate SDI Receiver which includes The output audio formats supported by the device include 2 complete SMPTE processing, as per SMPTE ST 425, AES/EBU and I S, and two other industry standard serial SMPTE ST 292 and SMPTE ST 259-C. The SMPTE processing digital formats. A variety of audio processing features are features can be bypassed to support signals with other provided to ease implementation. Audio clocks are coding schemes. internally generated and provided by the device. 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. The device operates in one of four basic modes: SMPTE mode, DVB-ASI mode, Data-Through mode or Standby mode. In SMPTE mode (the default operating mode), the GS2970A performs full SMPTE processing, and features a number of data integrity checks and measurement capabilities. The device also supports ancillary data extraction, and can provide entire ancillary data packets through host-accessible registers. It also provides a variety of other packet detection and error handling features. All of these processing features are optional, and may be individually enabled or disabled through register programming. Both SMPTE ST 425 Level A and Level B inputs are supported with optional conversion from Level B to Level A for 1080p 50/59.94/60 4:2:2 10-bit inputs.
