For the mathematically inclined, the signal/noise ratio (SNR) in a digital system is affected by time-base jitter in the following manner:

SNR = 20 log₁₀(2 T PI F Square Root(2 F₀/F_S))

where: T = RMS jitter PI = 3.1416 F = signal frequency F₀ = bandwidth of noise measurement (20kHz) F_S = sampling frequency (352,800Hz for 8x oversampling)—Robert Harley
