Crystal oscillator clock signal
WebMar 1, 2024 · The relationship is Δ f = ( f ×PPM)/10 6. Here PPM is the peak variation (expressed as ±), f is the center frequency (in Hz), and Δ f is the peak frequency variation (in Hz). For example, 100 ppm of 100 MHz represents a variation in frequency (Δ f) of 10 kHz. The maximum and minimum frequencies are therefore 100.01 and 99.99 MHz ...
