Notes: 18. Attenuation measured with sinusoidal input filter equal to 3/4 of measured jitter tolerance. Circuit
attenuates jitter at 20 dB/decade above the corner frequency. Output jitter can increase significantly
when more than 28 UI’s are input to the attenuator.
19. Measurement is not effected by the position of the Jitter Attenuator.
