Attenuation at 10 kHz Jitter frequency (Note 14 and 15)
Attenuator Input Jitter Tolerance (Note 14)
(Before Onset of FIFO Overflow or Underflow Protection)
Notes:
9. For input amplitude of 1.2Vpk to 4.14Vpk
10. For input amplitude of 0.5Vpk to 1.2Vpk, and 4.14Vpk to 5.0Vpk
11. For input amplitude of 1.07Vpk to 4.14Vpk
12. For input amplitude of 4.14Vpk to 5.0Vpk
13. Jitter tolerance increases at lower frequencies. See Figure 11.
14. Not production tested. parameters guaranteed by design and characterization.
15. Attenuation measured with sinusoidal input jitter equal to 3/4 of measured jitter tolerance.
Circuit attenuates jitter at 20 dB/decade above the corner frequency. See Figure 16. Output jitter
can increase significantly when more than 28 UI’s are input to the attenuator. See discussion in
jitter Attenuator section.
