Stratix GX Clocking
The Stratix GX global clock can be driven by certain REFCLKB pins, all
transmitter PLL outputs, and all receiver PLL outputs. The REFCLKB pins
(except for transceiver block 0 and transceiver block 4) can drive inter-
transceiver and global clock lines as well as feed the transmitter and
receiver PLLs. The output of the transmitter PLL can only feed global
clock lines and the reference clock port of the receiver PLL.

and EP1SGX40G devices. For devices with fewer transceivers, ignore the
information about the unavailable transceiver blocks.
