Function
Positive modulation current output (AC or DC coupled to cathode of laser in
common anode designs). Sinks current when D_IN+ is HIGH.
Maintain a voltage > 0.7V at this pin.

SV_CC
Negative modulation current output (AC coupled to anode of laser in common
cathode designs). Sinks current when D_IN- is HIGH
Maintain a voltage > 0.7V at this pin.
Switched VCC. Supplies laser current for common anode designs. (CC_SEL must
be LOW).
Provides redundant shutdown during a disable or fault condition. This switch is
disabled during common cathode operation.

V_CC
V_CC3
Laser bias current output for common cathode laser designs (CC_SEL must be
high).
Connect directly to laser anode or at higher bit rates through a ferrite or a
resistor to isolate the capacitance of this pin from the modulation drive.
Maintain a voltage of < 2.5V at this pin.
