Applications
Description
The GS1661 is a multi-rate SDI integrated Receiver which
includes complete SMPTE processing, as per SMPTE 292M
and SMPTE 259M-C. The SMPTE processing features can be
bypassed to support signals with other coding schemes.
The GS1661 integrates Gennum's 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 default operating mode), the GS1661
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
