In the case of not using "RFCLK" and "SYSREF+/-", how should I do these unused pins ?
Should I connect these pins to ground or open ?
Please let me know about this matter.
Fig. 49 shows an example where RFCLK is AC coupled. Therefore you can leave it open, when you do not use it.
High speed differential clocks are often AC coupled, so I think the same is true for the SYSREF inputs.
Thank you for your response. I am happy to get your comment.
