ELECTRICAL CHARACTERISTICS (continued)
(V
+25°C.) (Figure 1)
Note 1: Supply current excludes bias and modulation currents.
Note 2: Deterministic jitter is the peak-to-peak deviation from the ideal time crossings measured with a K28.5 bit pattern
Note 3: AC characteristics guaranteed by design and characterization.
