DS90UB949A-Q1EVM: Using with coaxial cable

Part Number: DS90UB949A-Q1EVM
Other Parts Discussed in Thread: DS90UB947-Q1, DS90UB928Q-Q1

Hi team,

1. Could you please let me know how to use DS90UB949A-Q1EVM with coaxial cable? I recognize the termination should be cared like datasheet 8.2.1. I know the cable type can be set by MODE_SEL. Anything else I need to set up?

2. Can DS90UB947-Q1 be paired with DS90UB928Q-Q1? I saw other people were struggling to pair them in the other thread.

Hello Itoh-san,

1) yes, this should be correct!

2) yes, this is possible. You just need to make sure you are using a single lane (not dual) and that the PCLK is supported by the UB928.
