RTIP/RRING Input Impedance
Sensitivity Below DSX (0dB = 2.4V)
Loss of Signal Threshold
Data Decision Threshold
Allowable Consecutive Zeros before LOS
Receiver Input Jitter Tolerance
Jitter Attenuator
Jitter Attenuation Curve Corner Frequency
Attenuation at 10kHz Jitter Frequency
Attenuator Input Jitter Tolerance (Before Onset
of FIFO Overflow or Underflow Protection)
21. For input amplitude of 0.5 V
22. For input amplitude of 1.05 V
23. Jitter tolerance increases at lower frequencies. See Figure 11.
24. Attenuation measured with input jitter equal to 3/4 of measured jitter tolerance. Circuit attenuates
jitter at 20 dB/decade above the corner frequency. See Figure 12. Output jitter can increase
significantly when more than 12 UI’s are input to the attenuator. See discussion in the text section.
