Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: The quiescent V
zero SRC pin current (i.e., the laser is operating with zero bias current and
zero modulation current). The total power supply current is the quiescent
current plus the SRC pin current, I

Note 3: The peak transient voltage at the IN
exceed the range of –300mV to V
Note 4: When Cml_en = 0 (not in CML mode), the termination is 100
differential with 50k common mode to V
Note 5: The common mode input resistance is measured relative to
V
Note 6: When Cml_en = 1 (CML mode), the termination is nominally 50

Note 7: The SRC pin current can be programmed to near zero in each
range, but the recommended minimum operating level is 1/16 of full scale.
Note 8: The laser bias current is the average current delivered to the laser.
It is equal to the SRC pin current minus the average modulation current at
the MODA and MODB pins, or I
therefore depends on Is_rng and the actual modulation current.
Note 9: The MODA and MODB pins are connected on-chip. The modulation
current refers to the sum of the currents on these pins. I
