Typical applications: Cameras, DC-coupling from 1.2V to 2.5V CML logic Switchers, Distribution Amplifiers and Routers. Trace Equalization to compensate for up to 60 FR4 at 2.97Gb/s Automatic input offset compensation GS3590 1 of 121 www.semtech.com Final Data Sheet Rev.6 Semtech PDS-061414 July 2018 Proprietary & ConfidentialWith high phase consistency between scans and Description configurable space and time thresholds, algorithms can be The GS3590 is a low-power, configurable multi-rate deployed in the field to analyse long-term signal quality re-timing Cable Equalizer/Cable Driver supporting rates up variation (Bathtub Plot) to reduce costly system installation to 3G-SDI. It can be configured to equalize or drive signals debug time for intermittent errors. 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 GS3590 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 GS3590 is pin compatible with the GS12090 The 256x128 resolution scan matrix allows accurate signal Bidirectional 12G-SDI Re-timing Adaptive Cable analysis to speed-up prototyping and enable field analysis.
