Function
GND_O
V_CC
Ground for output stage. May be connected directly to ground. At high bit rates
(>2Gb/s) an optional inductor or ferrite may be added to reduce switching
transients.
GND₀

V_CC
OUT+
Positive modulation current output. Sinks current when D_IN+ is HIGH.
Maintain a voltage > 1.6V at this pin when VCC3_SEL is high.
Maintain a voltage > 1.15V at this pin when VCC3_SEL is low.

V_CC
V_CC3
Negative modulation current output. Sinks current when D_IN- is HIGH
Maintain a voltage > 1.6V at this pin when VCC3_SEL is high.
Maintain a voltage > 1.15V at this pin when VCC3_SEL is low.
Switched V_CC.
3.3V applications - Connect to laser anode. Safety circuitry will open the switch
when a fault is detected and no current will flow through the laser.
No capacitance is needed on this node. If capacitance to ground is added, do not
exceed 100 pF.
SV_CC
5V applications - Disabled, leave open.
