Semtech GS12182 Re-timing Cable Drivers

Semtech GS12182 Re-timing Cable Drivers are low-power and multi-rate cable drivers that support rates of up to 12G UHD-SDI, inclusive of 10GbE. These drivers receive 100Ω differential input signals, automatically recover the embedded clock from the digital video signal and re-time the incoming data. These cable drivers then transmit the re-timed signal over 75Ω coaxial cables. The GS12182 cable drivers consist of an integrated eye monitor that provides non-disruptive mission mode analysis of the post equalized input signal. These cable drivers offer GSPI serial control and monitoring interface, 2.5V or 3.3V for cable driver output supply, and four configurable GPIO pins. Typical applications include cameras, switchers, distribution amplifiers, and routers.
