Semtech GS3281 3G-SDI Re-timing Cable Drivers

Semtech GS3281 3G-SDI Re-timing Cable Drivers are low-power and multi-rate re-timing devices. These devices are designed to receive 100Ω differential input signals that automatically recover the embedded clock from the digital video signal. The Semtech drivers re-time the incoming data and transmit the re-timed signal over 75Ω coaxial cable. The integrated eye monitor provides a non-disruptive mission mode analysis, and the 256 x 128 resolution scan matrix allows accurate signal analysis. These equalizers include built-in macros that enable customizable cross-section analysis and quick horizontal and vertical eye-opening measurements. The GS3281 drivers are pin-compatible with the GS12181, GS12281 single input, and the GS12182 dual input 12G UHD-SDI multi-rate Re-timing cable driver. These GS3281 drivers are ideally used in cameras, switchers, distribution amplifiers, and routers.
