19.6 Jitter Attenuator Characteristics
(TA = -40°C to 85°C; TV+, RV+ = 3.3 V ±5%; GND = 0 V)
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.
