Hi all,

I'm looking for a simple solution for an SDI-HD repeater with carrier-detect function.

The signal source is SDI-HD camera with BNC.

The output MUST be the same as the input signal, which means the circuit should not disturb the input signal.

Please, refer to the block diagram.

Do I have to design all of the SDI-HD re-clocker circuit? or is there any simple solution for it?

Thank you in advance.

Hi John,

Please consider using LMH0397 device. SDI from your camera could be connected to the SDI_IO pin. Then SDI_OUT would go to your DVR. Here is a link to the LMH0397 product folder:

1). Could you please let us know what is your camera model with SDI output?

2). To get detailed LMH0397 device data sheet, please send me email using your company email address. Here is my email address: Nasser.mohammadi@ti.com.
