Max input Voltage for single ended clock input (Stratix IV)

Hi We have an existing board containing a EP4SE360F35I3 (F1152 PACKAGE). I am trying to determine the maximum input Voltage that can be safely be fed into a dedicated clock input pin (single ended)....

​Hi,

Thanks you for getting back to me.

So just to confirm, we can safely feed a single ended clock signal (maximum 3.0V) into CLK8P and CLK10P?

(Both bank 5C and 6C use a Vccio of 2.5V.)

This should be safely within the ViH limit of 3.6V as shown in the table.

Best regards

Simon

    Hi Simon,

    Yes, you're right.

    Thanks
