GS3590中文资料Bidirectional 3G-SDI Re-timing Adaptive Cable Equalizer/Cable Driver数据手册Semtech规格书

描述 Description

The GS3590 is a low-power, configurable multi-rate re-timing cable equalizer/cable driver supporting rates up to 3G UHD-SDI. It can be configured to equalize or drive signals over 75Ohm coaxial cable. It includes DC restoration to compensate for the DC content of SMPTE pathological test patterns. Since the GS3590 is a re-timing device, extremely low output jitter is achievable even at extended cable/trace lengths.
