LMX2594EVM: I would like to request an exchange due to the suspicion of a defect.

Part Number: LMX2594EVM

Tool/software:

I'm contacting you because I think it needs to be exchanged because a suspected defect has been confirmed on the LMX2594EVM board.

Suspects identified are as follows.

Set up and run according to the LMX2594EVM User Guide, but does not operate normally

Chip Select signal remains low (normal operation requires High → Low transition)

At the Bias Level measurement, the Pin 3 voltage is found to be about 0.28V (normal operating voltage on the data sheet is about 1.3V)

For the above reasons, the board is suspected to be defective.

Also, I attached the PPT that summarized the contents of the conversation with the TI engineer and the measurement photo data as a reference.불량.pdf
