LMH0303: Sync issue in 3G-SDI Cable Driver

Farzad H

Part Number: LMH0303

Hello,

I use the LMH0303 as the cable Driver for a 3G-SDI camera. But time to time and sporadically I get multi images as follow!

While the Eye-Diagram still looks good!

What could be the reason?

    Hi Farzad,

    LMH0303 is a basic cable driver and works like a 50-ohm to 75-ohm converter. Therefor it does not have the intelligence to overlay or change video. I would consider looking at the FPGA or other ASIC that could be driving LMH0303 device.
