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.
