THVD1451: Schematic Review

Prem Kumar

Part Number: THVD1451

Tool/software:

Hello,

Please review the schematics of  THVD1451DRBR device used in my design for UART to RS422 interfacing. RS422 signals are connect to USB Type-C receptacle connector with specific pinouts decided by me.

Let me know if any termination resistor is required on the RS422 side. 

Regards,

Prem Kumar

    Hi Prem,

    I don't particularly see any issues with the schematic.

    Generally you want to place termination resistors on the receiver node of the RS422 side which would be the A/B pins. I would recommend placing it to the right of the 10 ohm resistors. Maybe 100 ohms, depends on what your cable's characteristic impedance is.
