Semtech GS12081
The GS12081 is a low-power, multi-rate, cable driver supporting rates up to 12G UHD-SDI. It is designed to receive 100Ω differential input signals, and transmit the signal over 75Ω coaxial cables. The 100Ω trace input supports up to 17dB of insertion loss.
The device supports SMPTE ST 2082-1 (12G UHD-SDI), ST 2081-1 (6G UHD-SDI), ST 424 (3G SDI), ST 292-1 (HD-SDI) and ST 259 (SD-SDI). In addition to standard SMPTE rates, the device also supports DVB-ASI at 270Mb/s, MADI at 125Mb/s, and 10GbE.
The two cable drivers have highly configurable pre-emphasis and swing controls to compensate for long trace and connector losses. Additionally, automatic and user selectable output slew rate control is provided for each cable driver output.
