Peak-to-peak (clock edge to clock edge)
Long term (averaged over 2 ms interval)
10 Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum f
sys.
Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal. Noise
injected into the PLL circuitry via VDDPLL and VSSPLL and variation in crystal oscillator frequency increase the Cjitter percentage
for a given interval.
11 Based on slow system clock of 40 MHz measured at f
