CLKLOCKX1_INPUT_FREQ

Creates an internal ClockLock phase-locked loop (PLL) and specifies its frequency. Turning this option

on is equivalent to instantiating an altclklock megafunction with either of its ClockBoost parameters set to

a value of 1. The CLKLOCKx1 Input Frequency option is provided primarily for backward compatibility

with MAX+PLUS II designs. Altera recommends using the MegaWizard Plug-In Manager to instantiate

PLLs in new designs. This option is ignored if it is assigned to anything other than an input pin or to a

device that does not have the PLL feature.
