Stratix II VCCSEL connection

Surfsup is correct. For more information refer to the Altera web site. Altera has published 3 known issues solutions to deal with this problem. Note that the affected text and table discussed in solutions rd03122007_78 and rd10112006_949 was originally written for PS and FPP mode but the documentation failed to clarify as such. In PS mode and FPP mode the lower trip point is selected by default independent upon VCCSEL pin setting. Altera is actively working to correct the handbook to minimize the impact to customers.
