ANALOG SPECIFICATIONS
Notes: 20. For input amplitude of 1.2 V

Receiver
RTIP/RRING Input Impedance
Sensitivity Below DSX (0dB = 2.4V)
Data Decision Threshold
Allowable Consecutive Zeros before LOS
Receiver Input Jitter Tolerance
Loss of Signal Threshold
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. The analog input squelch circuit shall operate when the input signal amplitude above ground on the
RTIP and RRING pins falls within the range of 0.25V to 0.50V. Operation of the squelch results in
the recovery of zeros. During receive LOS, the RPOS, RNEG or RDATA outputs are forced low.
