2 / 121 page  GS12190 Final Data Sheet Rev.3 PDS-061916 May 2020 2 of 121 Semtech Proprietary & Confidential www.semtech.com Description The GS12190 is a low-power, configurable multi-rate reclocking Cable Equalizer/Cable Driver supporting rates up to 12G UHD-SDI. It can be configured to equalize or drive signals over 75Ω coaxial cable. It includes DC restoration to compensate for the DC content of SMPTE pathological test patterns. Since the GS12190 is a reclocking device, extremely low output jitter is achievable even at extended cable/trace lengths. 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. With high phase consistency between scans and configurable space and time thresholds, algorithms can be deployed in the field to analyse long-term signal quality variation (Bathtub Plot) to reduce costly system installation debug time for intermittent errors. Each output has highly-configurable pre-emphasis and swing controls to compensate for long trace and connector losses. Additionally, automatic and user selectable output slew rate control is provided for the Cable Driver output. The GS12190 is pin compatible with the GS12090 and GS3590 Bidirectional 3G-SDI Reclocking Adaptive Cable Equalizer/Cable Driver.
