FUNCTION
Ground
Transmit Disable. Driver output is disabled when TX_DISABLE is high or left unconnected. The
driver output is enabled when the pin is asserted low.
Noninverted Data Input
Inverted Data Input
Fault Indicator. Open-drain output with ESD protection. FAULT is asserted high during a
fault condition.
Squelch Enable. Squelch is enabled when the pin is set high. Squelch is disabled when the pin is
set low or left open.
+3.3V Supply Voltage
Temperature Compensation Set Pin 1. A resistor placed between TC1 and TC2 (R TC ) programs the
temperature coefficient of the modulation current.
Temperature Compensation Set Pin 2. A resistor placed between TC1 and TC2 (R TC ) programs the
temperature coefficient of the modulation current.
Modulation Set. A resistor connected from MODSET to ground (R MODSET ) sets the desired
modulation current amplitude.
Peaking Current Set. A resistor connected between PEAKSET and ground (R PEAKSET ) programs
the peaking current amplitude. To disable peaking, leave PEAKSET open.
Inverted Modulation-Current Output
Noninverted Modulation-Current Output
Bias Current Set. When a closed-loop configuration is used, connect a 1.7k
resistor between
ground and BIASSET to set the maximum bias current. When an open configuration is used,
connect a resistor between BIASSET and ground (R BIASSET ) to program the VCSEL bias current.
Bias Current Output
Bias Current Monitor. The output of BIASMON is a sourced current proportional to the bias current.
A resistor connected between BIASMON and ground (R BIASMON ) can be used to form a ground-
referenced bias monitor.
Compensation Pin. A capacitor between COMP and MD compensates the APC. A typical value of
0.047 μF is recommended. For open-loop configuration, short the COMP pin to GND to deactivate
the APC.
Monitor Diode Connection
Reference Pin. Reference monitor used for APC. A resistor between REF and MD (R PWRSET ) sets the
photo monitor current when the APC loop is closed.
Average Power Monitor. The pin is used to monitor the transmit optical power. For open-loop
configuration, connect PWRMON to GND.
Exposed Pad. Ground. Must be soldered to the circuit board ground for proper thermal and
electrical performance. See the Layout Considerations section.
