Hi Team,
Please advise me on the questions bellows.
Q1. How much the maximum input leakage current on LVCMOS ipnuts such as TX_EN pin?
Q2. Is 75 ohm trace recommended on TERMRX connection despite of 220 ohm termination?

Hi Mita-san,
Thanks for yoru post and sorry for the delay. We will respond in the next few days as we get caught up.

Hi Mita-San,
1). Internal pull down or pull ups are in order of 60K Ohm to 130K Ohm.
2). Secondly, TERMRX is high impedance. So this trace does not need to be 75 ohm impedance. But please keep it as short as possible.
