3Gb/s, HD, SD-SDI Receiver Complete with SMPTE Video and Audio Processing

Overview

The GS2970 is a multi-rate SDI receiver which includes complete SMPTE processing, as per SMPTE 425M, 292M and SMPTE 259M-C. The GS2970 also performs audio-dembedding and integrates an audio clock generator.

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. The device operates in one of four basic modes: SMPTE mode, DVB-ASI mode, Data-Through mode or Standby mode.

In SMPTE mode, the GS2970 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.
