1.2.33. 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.
