Note 1: Characteristics at -40°C are guaranteed by design and characterization. Dice are tested at T A = +25°C only.
Note 2: Tested with R MODSET = 5.11k ? (I MOD ≈ 38mA), R BIASMAX = 4.56k ? (I BIAS ≈ 52mA), excluding I BIAS and I MOD .
Note 3: Both the bias and modulation currents will be disabled if any of the current set pins are shorted to ground.
Note 4: This assumes that the laser to monitor diode transfer function does not change with temperature.
Note 5: See Typical Operating Characteristics for worst-case distributions.
Note 6: AC characteristics are guaranteed by design and characterization.
Note 7: Total I MOD out of OUT+. Refer to the Design Procedure for information regarding current delivered to the laser.
Note 8: Input signal is a 622Mbps, 2 13 - 1 PRBS with 80 inserted zeros.
Note 9: Input signal is a 622Mbps, 11110000 pattern.
Note 10: PWD = (wider pulse – narrower pulse) / 2.
