An external 250-Ω pull-up resistor is not required, but recommended if signal levels on the board are not optimal.
Input buffer must be 3.3-V tolerant.
Input buffer must be 2.5-V tolerant.
Input buffer must be 1.8-V tolerant.

Stratix II devices contain dedicated circuitry for supporting differential
standards at speeds up to 1 Gbps. The LVDS and HyperTransport
differential I/O standards are supported in the Stratix II device. In
addition, the LVPECL I/O standard is supported on input and output
clock pins on the top and bottom I/O banks.
The high-speed differential I/O circuitry supports the following high
speed I/O interconnect standards and applications:

There are four dedicated high-speed PLLs in the EP2S15 to EP2S30
devices and eight dedicated high-speed PLLs in the EP2S60 to EP2S180
devices to multiply reference clocks and drive high-speed differential
SERDES channels.

can clock in each of the Stratix II devices. In
first row for each transmitter or receiver provides the number of channels
driven directly by the PLL. The second row below it shows the maximum
channels a PLL can drive if cross bank channels are used from the
adjacent center PLL. For example, in the 484-pin FineLine BGA EP2S15
