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).
Note 4: 2
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
Note 7: Unless otherwise specified, the pattern for all LOS detect specifications is 2
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
Note 10: Stability is defined as variation over temperature and power supply with respect to the typical gain of the part.
