GS3241中文资料3G-SDI Reclocking Adaptive Cable Equalizer数据手册Semtech规格书

描述 Description

The GS3241 is a low-power, multi-rate re-timing Cable Equalizer supporting rates up to 3G HD-SDI. It is designed to equalize and restore signals received over 200m coaxial cable at 3G, compensate for DC content of SMPTE pathological signals, and re-time the incoming data. The device supports ST 424 (3G SDI), ST 292-1 (HD-SDI), and ST 259 (SD-SDI) signals and is optimized for performance at 2.97Gb/s. In addition to standard SMPTE rates, the device also supports re-timing of DVB-ASI at 270Mb/s and MADI at 125Mb/s.
The two trace drivers have highly configurable pre-emphasis and swing controls to compensate for long trace and connector losses.
