Description
The GS12181 is a low-power, multi-rate, re-timing cable
driver supporting rates up to 12G UHD-SDI. It is designed to
receive 100 differential input signals, automatically
recover the embedded clock from the digital video signal
and re-time the incoming data, and transmit the re-timed
signal over 75 coaxial cables.
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). Automatic and user selectable output
slew rate control is provided for each cable driver output.
The device also supports transmission of MADI at 125Mb/s
and DVB-ASI.
