Part Number: SN65HVD75 Hi,
Customer raised below 2 questions.
1. Should the PIN A and B trace route as differential signal trace? Any trace impedance requirement?
2. Is PIN R required trace impedance control?
Best regards,
Randy Chen

Part Number: SN65HVD75 Hello
I attached a design file.
Could you review the design file for RS485 Repeater?
Maximum Baud rate is 115200.

Karthik,
I think common mode choke are commonly used for signal's transient behavior, while the ground potential difference is a DC bias. Here is an app note for common mode choke.
