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 the filter is not included in the DJ generation specification.
Note 4: Random jitter was measured without using a filter at the input.
Note 5: The supply current measurement excludes the CML output currents by connecting the CML outputs to a separate V
Note 6: Hysteresis is calculated as 10 log (V
Note 7: The signal is switched between two amplitudes, Signal_On and Signal _Off as shown in Figure 2.
Note 8: I
Note 9: Stability is defined as the variation over temperature and power supply with respect to the typical gain of the part.
