Note 1: Between sensitivity and overload, all AC specifications are met.  
Note 2: Guaranteed by design and characterization.  
Note 3: The deterministic jitter caused by this filter is not included in the DJ generation specifications (input).  
23  
Note 4:  
2
- 1 PRBS pattern was substituted by K28.5 pattern to determine the high-speed portion of the deterministic jitter. The  
low-speed portion of the DJ (baseline wander) was obtained by measuring the eye width difference between outputs gen-  
23  
erated using K28.5 and 2 - 1 PRBS patterns.  
Note 5: Random jitter was measured without using a filter at the input.  
Note 6: The supply current measurement excludes the CML output currents by connecting the CML outputs to a separate V  
(see Figure 1).  
CC  
23  
Note 7: Unless otherwise specified, the pattern for all LOS detect specifications is 2 - 1 PRBS.  
Note 8: The signal at the input is switched between two amplitudes, Signal_ON and Signal_OFF, as shown in Figure 2.  
Note 9:  
I
is the input common mode. I  
is the current at the RSSI output.  
CM_INPUT

Note 10: Stability is defined as variation over temperature and power supply with respect to the typical gain of the part.
