GS12081 12G UHD-SDI Cable Driver Key Features Applications Dual non-inverted 75 cable interface with on-chip Next Generation 12G UHD-SDI infrastructures designed to termination support UHDTV1, UHDTV2, 4K D-Cinema and 3D HFR and HDR production image formats. Typical applications: SMPTE ST 2082-1, ST 2081-1, ST 424, ST 292-1 and ST Cameras, Switchers, Distribution Amplifiers and Routers. 259 compliant input/output Multi-standard operation from 1Mb/s to 11.88Gb/s Description Cable driver features: The GS12081 is a low-power, multi-rate, cable driver Wide swing control supporting rates up to 12G UHD-SDI. It is designed to Pre-emphasis to compensate for significant receive 100 differential input signals, and transmit the insertion loss between device output and BNC signal over 75 coaxial cables. The 100 trace input supports up to 17dB of insertion loss. Manual output slew rate control The two cable drivers have highly configurable Manual or automatic Mute or disable on LOS pre-emphasis and swing controls to compensate for long Trace equalizer features: trace and connector losses. Additionally, user selectable Integrated 100, differential input termination output slew rate control is provided for each cable driver output. Automatic power down on loss of signal The GS12081 is pin compatible with the GS12181 and Adjustable carrier detect threshold GS12281 single input, and the GS12182 dual input 12G DC-coupling from 1.2V to 2.5V CML logic UHD-SDI Multi-rate Re-timing Cable Drivers, as well as the Trace equalization to compensate for up to 15 FR4 GS3281 3G SDI Multi-rate Re-timing Cable Driver. at 11.88Gb/s Note: For the GS12081 to be pin compatible with the Input offset compensation GS12182, careful design considerations are required.
