Semtech GS2960A

The GS2960A is a multi-rate SDI 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 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 full SMPTE processing, and features a number of data integrity checks and measurement capabilities.
The device also supports ancillary data extraction, and can provide entire ancillary data packets through host-accessible registers. It also provides a variety of other packet detection and error handling features. All of these processing features are optional, and may be individually enabled or disabled through register programming.
Both SMPTE 425M Level A and Level B inputs are supported with optional conversion from Level B to Level A for 1080p 50/60 4:2:2 10-bit.
In DVB-ASI mode, 8b/10b decoding is applied to the received data stream.
The device can also operate in a lower power Standby mode. In this mode, no signal processing is carried out and the parallel output is held static.
In Data-Through mode all forms of SMPTE and DVB-ASI decoding are disabled, and the device can be used as a simple serial to parallel converter.
Parallel data outputs are provided in 20-bit or 10-bit format for 3Gb/s, HD and SD video rates, with a variety of mapping options. As such, this parallel bus can interface directly with video processor IC's, and can be multiplexed onto 10 bits for a low pin count interface.
