The global clock line must be driven by an input pin.

Transmitter PLL Block
The transmitter PLLs in each transceiver block clock the PMA and PCS
circuitry in the transmit path. The Quartus II software automatically
powers down the transmitter PLLs that are not used in the design.

The transmitter phase/frequency detector references the clock from one
of the following sources:

Two reference clocks, REFCLK0 and REFCLK1, are available per
transceiver block. The inter-transceiver block bus allows multiple
transceivers to use the same reference clocks. Each transceiver block has
one outgoing reference clock which connects to one inter-transceiver
block line. The incoming reference clock can be selected from five
inter-transceiver block lines IQ[4..0] or from the global clock line that
is driven by an input pin.
