描述 Description

The GS12241 is a low-power, multi-rate re-timing Cable?Equalizer supporting rates up to 12G UHD-SDI. It is?designed to equalize and restore signals received over 80m?coaxial cable at 12G, compensate for DC content of SMPTE?pathological signals, and re-time the incoming data. The?device supports SMPTE ST 2082-1 (12G UHD-SDI), ST2081-1 (6G UHD-SDI), ST 424 (3G SDI), ST 292-1 (HD-SDI),?and ST 259 (SD-SDI) signals and is optimized for?performance at 11.88Gbps. In addition to standard SMPTE?rates, the device also supports re-timing of DVB-ASI at?270Mbps, and MADI at 125Mbps. The two trace drivers have highly configurable?pre-emphasis and swing controls to compensate for long?trace and connector?losses.
