There is a multiplexer here to select the PLL clock source. If a PLL uses this multiplexer to clock channels outside of
its bank quadrant, those clocked channels support up to 840 Mbps for “high” speed channels and 462 Mbps for
“low” speed channels, as labeled in the device pin-outs at www.altera.com.
