ELECTRICAL CHARACTERISTICS (continued)
(V
otherwise noted.) (Note 1)
Note 1: Specifications at -40°C are guaranteed by design and characterization. Dice are tested at T
Note 2: Maximum value is specified at I
Note 3: TX_FAULT is an open-collector output and must be pulled up with a 4.7kΩ to 10kΩ resistor.
Note 4: Guaranteed by design and characterization.
Note 5: V
Note 6: Gain stability is defined by the digital diagnostic document (SFF-8472, rev. 9.0) over temperature and supply variation.
Note 7: Assuming that the laser diode to photodiode transfer function does not change with temperature.
Note 8: Accuracy refers to part-to-part variation.
Note 9: Deterministic jitter is measured using a 2
Note 10: Broadband noise is filtered through the network as shown in Figure 3. One capacitor,
