Stratix IV Max Clock Input Voltage

Hi Simon,

The LVPECL VCCIO is given as 2.65 V ( page no:22 of the below document) , not the input voltage to the LVPECL standard

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/stratix-iv/stx4_5v4.pdf

The LVPECL standard is been characterized in 2.5V IO standard , not in 3 V IO standard.

So from Intel , it is not recommended to connect t o 3V IO standard to LVPECL.
