FUNCTION
The current into BIASMAX sets the maximum laser bias current. Connecting BIASMAX directly to REF1
allows the largest possible bias current.
The resistance (R TC ) between TC and REF1 programs the temperature coefficient of REF2. Connecting
TC directly to REF1 produces the minimum tempco. Leaving TC unconnected produces the maximum
tempco.
REF2 is the reference voltage used to program the modulation current. The tempco of REF2 is pro-
grammed by R TC .
The current into MOD programs the laser modulation current. Connect MOD to REF2 with a resistor or
potentiometer.
Ground. All grounds must be connected.
Inverting Data Input
Noninverting Data Input
Positive Supply Voltage. All V CC pins must be connected.
ENABLE is a TTL-compatible input. When low or open, this pin disables the output modulation and bias
current.
A capacitor to ground at SAFETY determines the turn-on delay for the safety circuits. If SAFETY is
grounded or TTL low, internal safety shutdown features are disabled. A TTL high at SAFETY enables the
internal safety shutdown features.
The FAIL output asserts low if the voltage at MD is above or below nominal. FAIL also asserts if REF1 is
inadvertently tied to the positive supply. FAIL has TTL-compatible output voltage levels.
Supply Voltage for the Output Current Drivers
Inverting Modulation-Current Output
Noninverting Modulation-Current Output
Connection for the DC Laser Bias Current
Ground for the Output Current Drivers
Input for the laser monitor photodiode current.
The current into POWERSET programs the average optical output power when automatic power
control is used.
REF1 is a voltage reference used to program laser bias current and average power.
