Stratix Device Handbook, Volume 2
You can power up or power down the V
sequence. The power supply ramp rates can range from 100 ns to 100 ms.
During hot socketing, the I/O pin capacitance is less than 15 pF and the
clock pin capacitance is less than 20 pF.
DC Hot Socketing Specification
The hot socketing DC specification is | I
AC Hot Socketing Specification
The hot socketing AC specification is | I
This specification takes into account the pin capacitance, but not board
trace and external loading capacitance. Additional capacitance for trace,
connector, and loading must be considered separately.
I
specification applies when all VCC supplies to the device are stable in the
powered-up or powered-down conditions. For the AC specification, the
peak current duration because of power-up transients is 10 ns or less. For
more information, refer to the Hot-Socketing & Power-Sequencing Feature &
Testing for Altera Devices white paper.
Although single-ended, non-voltage-referenced I/O standards do not
require termination, Altera recommends using external termination to
improve signal integrity where required.

Voltage-Referenced I/O Standards
Voltage-referenced I/O standards require both an input reference
voltage, V
board should be used for series and parallel termination.
