TUSB1064RNQEVM: Evaluation board schematic

Part Number: TUSB1064RNQEVM
Other Parts Discussed in Thread: TUSB1064, TPS2001C

Hi Supporting team,

I have purchased TUSB1064RNQEVM evaluation board to evaluate the USB Type-C implementation. With reference to the schematic drawing inside the User guides - "TUSB1064RNQ EVM User's Guide" at 14 Mar 2018, we found that the PCB components reference designator in the evaluation board are not matched with schematic drawing. Could you provide the update schematic drawing as we want to know the component placement/setting in the evaluation board. Thanks.

Regards,

Calvin

Hello Calvin,

What PCB components did you find that were different from the schematic drawing?

Hi Michael,

Thank you very much for the prompt reply.

Actually, there are a huge number of PCB components are not matched with the schematic drawing.

Here is an example for your reference.

Refer to schematic, the crosspoint switch TUSB1064 pin 21 and 22 are connected to R76 and R78 respectively. However, in the PCB, it is connected to R3 and R5.

Refer to schematic, U9 should be TPS2001C and the package is MSOP8. However, in the PCB, it is TPS7A4501 and the package is TO-263.

Regards,

Calvin

Thank you for bring this to my attention. Attached below should be the correct users guide with correct schematic. HSDC025A-002_UserGuide.docx

Dear Michael,

Many thanks for your support.

I think the evaluation board bought from distributor is previous version and that's why the schematic is not equivalent to the PCB. Thanks.

Calvin
