Applications
Description
The GS2960A is a multi-rate SDI Receiver which includes
complete SMPTE processing, as per SMPTE 425M, 292 and
SMPTE 259M-C. 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 GS2960A performs SMPTE
de-scrambling and NRZI to NRZ decoding and word
alignment. Line-based CRC errors, line number errors, TRS
errors and ancillary data check sum errors can all be
detected. The GS2960A also provides ancillary data
extraction. The entire ancillary data packet is extracted,
and written to host-accessible registers. Other processing
functions include H:V:F timing extraction, Luma and
Chroma ancillary data indication, video standard
detection, and SMPTE 352M packet detection and
decoding. All of the processing features are optional and
may be enabled or disabled via the Host Interface.
