SDI Signal multiplexing

Adrian Helwig

Hello Team,

my customer is looking for a way to multiplex two 75Ohm HD-SDI signals (see attachment).

On the ouput they wanted to have those two original input signals and additionally a copy of one of those signals (selected with select pin)

Any idea?

thanks and regards

Hi Adrian,

I responded to a similar request yesterday. Here is a link to this discussion:

Hi Nasser,
thanks, just one question regarding the passive 75Ohm SE to 100Ohm differential conversion:
from the SE 75Ohm source I connect 42.3Ohm in series to Pin IN0+ and 82.5Ohm from Pin IN0+ to ground. Pin IN0- with 50Ohm to ground, correct?

Thanks and Best Regards,
Hans

Hi Hans,

I have attached 75-ohm to 100-ohm differential min-loss pad.
