DESCRIPTION
The GS1504 is a high performance cable equalizer
designed to equalize HDTV component signal conforming
to SMPTE 292M. The adaptive cable equalizer is capable of
equalizing up to 100m of Belden 8281 co-axial cable.
The GS1504 features DC restoration for immunity to the DC
content in pathological test patterns. The device also
incorporates a Cable Length Indicator signal that provides
an indication of the amount of cable being equalized.
A voltage programmable mute threshold (MCLADJ) is
included to allow muting of the GS1504 output when a
selected cable length is reached. This feature allows the
GS1504 to distinguish between low amplitude HD SDI
signals and noise at the input of the device. The CD/Mute
pin provides an indication of the GS1504 mute status in
addition to functioning as a mute control input. The output
of the GS1504 may be forced to an active or a mute
condition by applying a voltage to the CD/Mute pin.
The GS1504 is a low power device that operates from a
single 5V power supply. The GS1504 is packaged in a
16 pin narrow SOIC and does not need external pull-up
resistors.
