Dice are tested at T A = +25°C only.
Tested at R MODSET = 2.49k ? , R BIASMAX = 1.69k ? , excluding I BIAS and I MOD .
Voltage on BIAS pin is (V CC - 1.6V).
Both the bias and modulation currents will be switched off if any of the current set pins are grounded.
Accuracy refers to part-to-part variation.
Assuming that the laser to monitor-diode transfer function does not change with temperature. Guaranteed by design and
characterization.
AC characteristics are guaranteed by design and characterization.
Measured with 622Mbps 0-1 pattern, LATCH = high.
PWD = (wider pulse - narrower pulse) / 2.
Note 10: See Typical Operating Characteristics for worst-case distribution.
