FUNCTION
Analog Supply Voltage
Noninverted Data Input, LVPECL Compatible
Inverted Data Input, LVPECL Compatible
Signal Supply Voltage
Noninverted Burst-Enable Input, LVPECL Compatible
Inverted Burst-Enable Input, LVPECL Compatible
Burst-Enable Output, LVCMOS. Signal replicates BEN input.
Enable Input LVCMOS. Active low enables BIAS± and OUT± outputs.
Bias Current Monitor. Current out of this pin develops a ground-referenced voltage across an
external resistor proportional to the bias current.
Current-Limit Reference. Connect a resistor from IMAX to GND to set maximum I BIAS plus I MOD .
Monitor Diode Out. Analog Output for sample/hold.
Monitor Diode In. Analog Input for sample/hold.

Supply Ground. This pin must be connected to ground.
Modulation Current Set. Current from this pin to ground sets the laser modulation current.
MODSET Reference. A ground-referenced voltage at this point establishes the MODSET reference.
Reference Voltage Output. May be used for VMSET, VBSET.
BIASSET Reference. A ground-referenced voltage at this point establishes the BIASSET reference.
Bias Current Set. Current from this pin to ground sets the laser bias current.
Exposed Paddle (Ground). The exposed pad must be soldered to the circuit board ground for proper
thermal and electrical operation.
