Notes to Table 16:
(1)
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.
The fCLKDEV parameter specifies how much the incoming clock can differ from the specified frequency during
device operation. Simulation does not reflect this parameter.
(2)
Twenty-five thousand parts per million (PPM) equates to 2.5% of input clock period.
(3)
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 tLOCK value is less than the time required for configuration.
(4)
The tJITTER specification is measured under long-term observation.
Tables 17 and 18 summarize the ClockLock and ClockBoost parameters
for APEX 20KE devices.
