ZCU106 : FMC LVDS/LVCMOS18

Jump to solution

Hello,

On the ZCU106 board, there are 2 FMC connecteurs J5 & J4. for instance, I wish to use the FMC_HPC0_CLK1_M2C_P pin as a single ended LVCMO18 input or output. The user guide says it a LVDS pin.

Is that possible?

Thanks.

Hi @sebo ,

You can still use that MC_HPC0_CLK1_M2C_P pin as Single ended LVCMOS18 input or output, it will work. Ensure you will give VADJ of 1.8V.

Note : Ensure you don't use clock signals as single ended IO standard on N pin.

Hope this helps.

In a related question, is it acceptable to use the 'LVCMOS18' pins for LVDS signals, assuming the voltage is correct?  The board routing appears to be differential.
