CIRCUIT DESCRIPTION
The GS9064 is a second-generation high-speed bipolar
integrated circuit designed to equalize and restore 270Mb/s
signals received over 75鈩?co-axial cable. The GS9064 is
designed to support both SMPTE 259M-C and DVB-ASI
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 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 MUTE/CD 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 MUTE/CD pin.
