Description
The GS2970A 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 default operating mode), the GS2970A
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
50/59.94/60 4:2:2 10-bit inputs.
In DVB-ASI mode, sync word detection, alignment and
8b/10b decoding is applied to the received data stream.
In Data-Through mode all forms of SMPTE and DVB-ASI
processing are disabled, and the device can be used as a
simple serial to parallel converter.
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.
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 ICs, and output data can be multiplexed
onto 10 bits for a low pin count interface.
Up to eight channels (two audio groups) of serial digital
audio may be extracted from the video data stream, in
accordance with SMPTE 272M-C and SMPTE 299M.
The output audio formats supported by the device include
AES/EBU and I2S, and two other industry standard serial
digital formats. A variety of audio processing features are
provided to ease implementation. Audio clocks are
internally generated and provided by the device.
