Note 1: Dice are tested at T
Note 2: Tested at R
Note 3: Voltage on BIAS pin is (V
Note 4: The bias and modulation currents will be switched off if any of the current set pins are grounded.
Note 5: Accuracy refers to part-to-part variation.
Note 6: Assuming the laser-to-monitor diode transfer function does not change with temperature. Guaranteed by design and
Note 7: AC characteristics are guaranteed by design and characterization using the characterization circuit of Figure 2.
Note 8: Measured with repeating 0000 1111 pattern, LATCH = high.
