Description
The GS2961 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 GS2961 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.
