Semtech GS3590
可配置型 3G-SDI 时钟恢复型自适应电缆均衡器/电缆驱动器
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 75Ω 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.
