Description
The GS2971 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 GS2971 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.
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 GS2971 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 GS2971 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.
Both SMPTE 425M Level A and Level B inputs are
supported. The GS2971 also provides user-selectable
conversion from Level B to Level A for 1080p 50/60 4:2:2
10-bit formats only.
In DVB-ASI mode, 8b/10b decoding is applied to the
received data stream.
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.
The device can also be placed in a lower power Standby
mode. In this mode, no signal processing is carried out and
the parallel output is held static. Placing the Receiver in
Standby mode will automatically place the integrated
equalizer in power down mode as well.
Parallel data outputs are provided in 20-bit or 10-bit
multiplexed format for 3Gb/s, HD and SD video rates. For
1080p 50/60 4:2:2 10-bit, the parallel data is output on the
20-bit parallel bus as Y on 10 bits and Cb/Cr on the other 10
bits. As such, this parallel bus can interface directly with
video processor ICs. For other SMPTE 425M mapping
structures, the video data is mapped to a 20-bit virtual
interface as described in SMPTE 425M. In all cases this
20-bit parallel bus can be multiplexed onto 10 bits for a low
pin count interface with downstream devices. The
