Enabling 3Gb/s Data Rates at HD Cable Runs

Overview

The GS2971A is a multi-rate SDI integrated Receiver which includes complete SMPTE processing, as per SMPTE 425M, 292M and SMPTE 259M-C. The SMPTE processing features can be bypassed to support signals with other coding schemes.

The GS2971A integrates Gennum's adaptive cable equalizer technology, achieving unprecedented cable lengths and jitter tolerance. It features DC restoration to compensate for the DC content of SMPTE pathological signals.

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 GS2971A performs full SMPTE processing, and features a number of data integrity checks and measurement capabilities.
