3.2.5. Global Clock or Core Clock as an Input Reference Clock

The global clock or the core clock can be used as an input reference clock for ATX PLL and fPLL.

The global or core clock network routes the clock directly to the PLL. In this case the PLL reference clock network is not used. For best performance, use the dedicated reference clock pins or the reference clock network.
