1.May I only use TX/RX(SOUT/SIN) for TUSB3410 UART, and other control pin don't care (CTS,RTS…)?

2. Could I not use SN75LV4737A line driver for EVM circuit ?

3.Could I not use EEPROM for EVM circuit?

Hello,
Yes, you can only use RX/TX
I can't comment on the re-driver, I recommend you to post a question on the High Speed Interface e2e Forum.
The EEPROM is required to load the firmware, Can you elaborate more on your implementation?
Regards

Hello,
A couple of comments:
1. Terminal VDD18 must have a capacitor to GND.
2. You have to follow the power-up sequence described on Section 13.4 in Datasheet.

Dear Sirs
Thank you for your comments.

1. If tie the VREG to GND(internal 1.8V), we still want to have capacitor to VDD18 ? If Capacitor is needed for VDD18, what value you preferred to use ?

2. I am not sure the reset timing for our design is meet or not, could you advise me if design needs to improve, thanks a lot..
