Title: TE0703-05 Output voltage
Post by: sonic on March 08, 2018, 03:33:24 PM

Hello,

We are using TE0703-05 Carrier card. Our requirement is to get 3.3V output signal level of SPI on the J2C connector. I am only using Bank13 FPGA pins for this.
I have already assigned LVCOMS33 in the constraints file, But when I measured the output signal it's only 1.8V. believe it's because J5, J8, J9, J10 jumpers are connected to the 1.8V position.

Can anyone please guide me which jumper needs to be changed?

Appreciate your help!

Best Regards

Update,

Signal level jumped to 3.3V after changing J10 to 3.3V

Best Regards
