Description
The GS12341 is a low-power, multi-rate reclocking Cable Equalizer supporting rates up to 12G UHD-SDI. It is designed to equalize and restore signals received over 80 meters coaxial cable at 12G, compensate for DC content of SMPTE pathological signals, and reclock the incoming data.
The integrated eye monitor provides non-disruptive mission mode analysis of the post equalized input signal. The 256x128 resolution scan matrix allows accurate signal analysis to speed up prototyping and enable field analysis.
