+3.3V, 2.5Gbps Low-Power Laser Driver
AC ELECTRICAL CHARACTERISTICS
(VCC = +3.14V to +3.6V, TA = -40°C to +85°C. Typical values are at VCC = +3.3V, IBIAS = 60mA, IMOD = 30mA, TA = +25°C, unless
otherwise noted.) (Notes 5, 6)

Note 1: Specifications at -40°C are guaranteed by design and characterization. Dice are tested at TA= +25°C only.
Note 2: Both the bias and modulation currents are switched off if any of the current set pins is grounded.
Note 3: Guaranteed by design and characterization.
Note 4: Accuracy refers to part-to-part variation.
Note 5: AC characterization was performed by using the circuit in Figure 2.
Note 6: AC characteristics are guaranteed by design and characterization, and measured using a 2.5Gbps 213 - 1 PRBS input data
pattern with 80 consecutive zeros and 80 consecutive ones added.
Note 7: Measured using a 2.5Gbps repeating 0000 1111 pattern.
Note 8: PWD = (wide pulse - narrow pulse) / 2.
