Tool/software:

Hello Everyone,

I'm using LMH1219 as a repeater to increase the intermediate cable reach.

As while designing I came across that the input to the INT0 75 ohms and INT1 is 100 ohms, and the output of both the channel is 100 ohms.

Please suggest me some solutions, as the internal termination resistor of OUT0 and OUT1 is 100 ohms.

I want dual channel driver both of 75 ohms input and 75 ohms output.

How i can use LHM1219 as a repeater for 2 channel 75 ohms input and 75 ohms output?

Hi Mishra,

I believe i already responded to this case. Please use LMH1297 instead. LMH1297 SDI_IO can be used for cable equalizer and SDI_OUT can be used for the cable driver.
