To implement the ClockLock and ClockBoost circuitry with the Quartus II software, designers must specify the
input frequency. The Quartus II software tunes the PLL in the ClockLock and ClockBoost circuitry to this frequency.

Twenty-five thousand parts per million (PPM) equates to 2.5% of input clock period.
During device configuration, the ClockLock and ClockBoost circuitry is configured before the rest of the device. If
the incoming clock is supplied during configuration, the ClockLock and ClockBoost circuitry locks during
configuration because the t
