DESCRIPTION
The GS7000 is a dual function IC capable of operating as
either a 270Mb/s Serial Digital Video receiver or a 270Mb/s
Serial Digital Video transmitter. The GS7000 is designed so
that it can be programmed to operate in either receive or
transmit mode via a mode select pin.
When operating as a receiver, the serial data input accepts
SMPTE 259M-C compliant signals. Line terminations are on
the device. An on-chip by-passable fixed gain equalizer
provides cable equalization beyond 100m of high quality
co-axial cable. The clock recovery is performed on chip
with minimal external components. Incoming Serial Digital
Video data is decoded using a NRZI decoder and SMPTE
descrambler to provide clocked SMPTE 125M compliant
parallel output. The SMPTE descrambler and NRZI
decoding functions can be disabled.
When operating as a transmitter, the GS7000 accepts
parallel SMPTE 125M compliant ten bit video. An on-chip
scrambler and NRZI encoder converts the parallel data into
a bit serial SMPTE 259M-C compliant NRZI output signal
suitable for driving co-axial cable. Through the SMPTE
select pin, the SMPTE scrambler and NRZI coding functions
can be disabled.
