TXS02612：About the circuit configuration

user6006290
Prodigy 40 points
Part Number: TXS02612

We are currently considering a circuit using TXS02612 to connect Xilinx XC7Z030 -1 FFG 676 I from the MicroSD card slot.

I referred to the circuit diagram of zedboard of xilinx, but there are some parts I don't understand, so I asked you.
The questions are as follows.

1.Do I need to pull up the CMDB0 signal?
If necessary, please tell me the reason for pull-up.

2.Is resistance required between CLKA and FPGA?
How do you determine this resistance value?

3.Is there a recommended resistance for the SEL PD?

4.Is there a recommended circuit for TXS02612?

zedboard schematic for reference

Thank you very much.

    Hi Makoto,

    It seems like you are asking questions specific to that design, I can't really comment on their reference design since it didn't come from TI. All the info you need to implement this device is located in the data sheet. The implementation can be as simple as the diagram shown on page 2 of the data sheet.
