10G-EXPANSION-EVM: User manual for 10G-EXPANSION Evaluation Module is not consistent with the real thing

user6037031

Part Number: 10G-EXPANSION-EVM
Other Parts Discussed in Thread: TUSB1064

Hi. Community members.

I am thinking of converting USB-C to DisplayPort.
I am trying to achieve this using the 10G-EXPANSION Evaluation Module.
Please help me as I was in trouble.

The schematic and BOM in the user manual are not consistent with the actual product.
There are a lot of parts that are not in real though they are in the schematic and BOM.
There are also a lot of mistakes when the pin assignment of IC is wrong.
Under the present circumstances, I can not evaluate correctly.

Could you provide the latest correct user guide, BOM?

Best Regards.

    Hello,

    Would you be able to elaborate more on the inconsistencies you are seeing? As far as I know, what's included within the user's manual should be the latest and greatest.

    Hi. Adam

    Thank you for your reply.
    Specifically, there is the following inconsistencies.

    ● Parts described in the circuit diagram and BOM but not mounted
    R13_BA, R13_BB, R14_BA, R14_BB, R15_BA .R15_BB, R16_BA, R16_BB
    R18, R19, R20, R22, R25, R32, R40, R43, R44, R46, R49, R57,etc

    ● BA and BB in the circuit diagram and BOM are reversed in sink and source
    J5_BA, J5_BB, R12_BA, R12_BB, etc.

    Best Regards.

    The resistors are depopulated so that the base build works as expected with our other EVM's (TPS65987DEVM), but we have other 0 ohm resistors in case our customers would like to test other functionality

    For example, R20 through R24 control how the TUSB1064 is controlled. The based project files for the TPS65987DEVM control this MUX via GPIO and not I2C, so we depopulate the 0 ohm resistors to where the TUSB is connected to the GPIO lines and not the I2C lines.
