Hi Team

Would you advise whether LMH1297 has out0+/- outputs with 75 ohm termination option?

Thanks

Hi Shidara-San,

OUT0+/- impedance is 100-ohm differential impedance. As you know, SDI_OUT or loop through output is a 75-ohm cable driver. Could you please let me know the application or why you need OUT0 to be 75-ohm driver - on top of SDI_OUT.

Hi Shidara-San,
This application may require SDI input and then 4 or 2 positive SDI output. For this, we can recommend using one LMH1297 plus another LMH1228 device.
