Other Parts Discussed in Thread: LMH0307, LMH0344,
hello, I am trying to equalize, re-clock and split SDI signals. The input is a single ended HD-SDI signal passed via a 75Ohm track. Now, the cable equalizer converts it into a differential signal which is 100 ohms. For this I am using the LMH0344, LMH0346 and LMH0307. I came across a post in this forum regarding a similar query. The post -
Now, the post states that LMH0307 accepts 50 Ohm signal. How so ? Could you point to the portion in the datasheet that states so ? Now, supposing I use the LMH0344 followed by LMH0346 and LMH0307. The LMH0344 will be given a single ended 75Ohm HD-SDI data. This will convert single ended data to differential (100 ohm). The LMH0346 will reclock and drive differential signals (HD-SDI) to LMH0307. This will finally split the HD-SDI to 2 different signals. Is my understanding correct ? In the forum it is mentioned that LMH03466 expects 50Ohm input. If it is differential, how can it accept 50 Ohm ? Also, how is SDI differential pair ?
