GS2961A
Semtech GS2961A
3G-, HD-, SD-SDI and DVB-ASI Receiver, with Integrated Adaptive Cable
Equalizer
Add to W a tch List
The GS2961A is a multi-rate SDI integrated Equa lizer-Receiver w hich includes complete SMPTE processing,
as per SMPTE 425M (Leve l A and Level B), SMPTE 424M, 292M and SMPTE 259M-C.
The SMPTE proce ssing fe a tures ca n be bypassed to support signals w ith other coding schemes.
The GS2961A inte grates Gennum's ne xt-generation sta te-of-the -art adaptive cable equalization technology,
achieving unprecedented cable lengths and jitter tolerance. It features DC resto ra tion to compensate for
the DC content of SMPTE pathological signa ls.
The de vice features an Inte grated Re clocke r w ith an internal VCO and a w ide Input Jitter Tolerance (IJT) of
0.7UI. A serial digital loop through output is provide d, w hich can be configured to output eithe r reclocked or
non-reclocked se rial digital da ta. The Se rial Digital Output can be connected to an e xternal Cable Driver.
The de vice operates in one of four basic mode s: SMPTE mode, DVB-ASI mode , Da ta-Through mode or
Standby mode .
In SMPTE mode , the GS2961 performs SMPTE de-scrambling and NRZI to NRZ de coding and w ord alignment.
Line-based CRC errors, line numbe r e rrors, TRS errors and ancillary data check sum errors ca n all be
detected. The GS2961A also provide s ancillary da ta extraction. The entire ancillary data packet is extracted,
and w ritten to host-accessible registers. Other processing functions include H:V:F timing e xtraction, Luma
and Chroma ancillary da ta indication, vide o standard de tection, and SMPTE 352M packe t dete ction and
decoding. All of the processing features are optional, and may be e nabled or disa bled via the Hos t
Interfa ce .
