Note 1: Electrical specifications are production tested at T A = +25°C. Specifications over the entire operating temperature range
are guaranteed by design and characterization. Typical specifications are at T A = +25°C, 3.3V.
Note 2: For 10mA ≤ I MOD ≤ 85mA and 4mA ≤ I BIAS ≤ 70mA.
Note 3: Deterministic jitter measured with a continuous pattern of 2 7 -1 PRBS, 80 ones, 2 7 -1 PRBS, 80 zeros at 1.25Gbps, and both
LVPECL inputs terminated by the network shown in Figure 3.
Note 4: Random jitter, rise time, fall time measured with 0000011111 pattern at 1.25Gbps.
Note 5: Voltage difference between VMSET and MODSET or VBSET and BIASSET excluding IR drops. The maximum operating
voltage at VMSET or VBSET must be less than 1.4V for proper operation.
Note 6: Turn-on/-off time is when the BEN+/BEN- LVPECL inputs are used to control modulation and bias currents.
Note 7: Burst-enable delay is measured between the time at which the rising edge of the differential burst-enable input reaches the
midpoint, and the time at which the combined output currents (bias plus modulation) reach 90% of their final level.
Note 8:
Burst-disable delay is measured between the time at which the falling edge of the differential burst-enable input reaches the
midpoint, and the time at which the combined output currents (bias plus modulation) fall below 10% of the bias-on current.
Note 9: Droop measured with sample/hold output load of 10M Ω .
Note 10: Enable delay is measured between the time at which the falling edge of the EN input reaches ≤ 0.8V, and the time at which
the combined output currents (bias plus modulation) reach 90% of their final level.
Note 11: Disable delay is measured between the time at which the rising edge of the EN input reaches ≥ 2V, and the time at which
the combined output currents (bias plus modulation) fall below 10% of the bias-on current.
Note 12: Excelight SLT2886-LR laser.
Note 13: Current gain stability = [(Gain – nominal Gain) / nominal Gain], nominal Gain at V CC = 3.3V, T A = +25°C.
Note 14: Gain linearity = (Gainmax – Gainmin), Gainavg = Gainmax + Gainmin
Gainavg 2
Note 15: Gain matching = Gain mod / Gainbias ? Gain mod nom / Gainbiasnom , nominal at V CC = 3.3V, T A = +25°C.
