the differential steady-state voltage (peak-to-peak).
Programmable Termination
The programmable termination can be statically set in the Quartus II
software. The values are 100 Ω , 120 Ω , 150 Ω , and external termination.

PCI Express Receiver Detect
The Stratix II GX transmitter buffer has a built-in receiver detection circuit
for use in PIPE mode. This circuit provides the ability to detect if there is
a receiver downstream by sending out a pulse on the channel and
monitoring the reflection. This mode requires the transmitter buffer to be
tri-stated (in electrical idle mode).
PCI Express Electric Idles (or Individual Transmitter Tri-State)
The Stratix II GX transmitter buffer supports PCI Express electrical idles.
This feature is only active in PIPE mode. The tx_forceelecidle port
puts the transmitter buffer in electrical idle mode. This port is available in
all PCI Express power-down modes and has specific usage in each mode.
