DESCRIPTION
The GS9064 is a second-generation high-speed bipolar
integrated circuit designed to equalize and restore signals
received over 75? co-axial cable at data rates from
143Mb/s up to 540Mb/s. The GS9064 is designed to
support SMPTE 344M and SMPTE 259M and is optimized
for performance at 270Mb/s.
The GS9064 features DC restoration to compensate for the
DC content of SMPTE pathological test patterns, and
incorporates a Cable Length Indicator (CLI) that provides a
linear indication of the amount of cable being equalized.
A voltage programmable mute threshold (MCLADJ) is
included to allow muting of the GS9064 output when a
selected cable length is reached. This feature allows the
GS9064 to distinguish between low amplitude SDI signals
and noise at the input of the device. The CD/MUTE pin
provides an indication of the GS9064 mute status in
addition to functioning as a mute control input. The output
of the GS9064 may be forced to an active or a mute
condition by applying a voltage to the CD/MUTE pin.
