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 next-generation
state-of-the-art 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.
