ELECTRICAL CHARACTERISTICS (continued)
(V CC = +2.97V to +3.63V, T A = -40°C to +85°C. Typical values at V CC = +3.3V, I BIAS = 20mA, I MOD = 30mA, T A = +25°C, unless
otherwise noted.) (Note 1)

Note 10:
Specifications at -40°C are guaranteed by design and characterization. Dice are tested at T A = +25°C only.
Maximum value is specified at I MOD = 60mA, I BIAS = 100mA.
TX_FAULT is an open-collector output and must be pulled up with a 4.7k ? to 10k ? resistor.
Guaranteed by design and characterization.
V CC turn-on time must be ≤ 0.8s, DC-coupled interface.
Gain stability is defined by the digital diagnostic document (SFF-8472, rev. 9.0) over temperature and supply variation.
Assuming that the laser diode to photodiode transfer function does not change with temperature.
Accuracy refers to part-to-part variation.
Deterministic jitter is measured using a 2 23 - 1 PRBS or equivalent pattern.
Broadband noise is filtered through the network as shown in Figure 3. One capacitor,
C < 0.47μF, and one 0603 ferrite bead or inductor can be added (optional). This supply voltage filtering reduces the hot-
plugging inrush current. The supply noise must be < 100mV P-P up to 2MHz.
Note 11: C APC values chosen as shown in Table 4 (MAX3735A).
