It can be configured to equalize or drive debug time for intermittent errors. signals over 75 coaxial cable. It includes DC restoration to Each output has highly configurable pre-emphasis and compensate for the DC content of SMPTE pathological test swing controls to compensate for long trace and connector patterns. Since the GS12090 is a re-timing device, extremely losses. low output jitter is achievable even at extended cable/trace lengths. Additionally, automatic and user selectable output slew rate control is provided for the Cable Equalizer output. The integrated Eye Monitor provides non-disruptive mission mode analysis of the post-equalized input signal. The GS12090 is pin compatible with the GS3590 The 256x128 resolution scan matrix allows accurate signal Bidirectional 3G-SDI Re-timing Adaptive Cable analysis to speed-up prototyping and enable field analysis.
