概要

The GS12142 is a low-power, multi-rate equalizer that features an integrated cable equalizer, trace equalizer, and trace driver supporting rates up to 12G UHD-SDI, inclusive of 10GbE.

The cable equalizer input is designed to equalize and restore signals received over 80m coaxial cable at 12G, compensate for DC content of SMPTE pathological signals, and re-time the incoming data. The trace equalizer input is designed to receive 100Ω differential input signals, automatically recover the embedded clock from the digital video signal and re-time the incoming data, supporting up to 17dB of insertion loss.

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. Built in macros enable customizable cross section analysis and quick horizontal and vertical eye opening measurements.
