NAME
GND
FUNCTION
1, 10, 13
Ground
2
TX_DISABLE
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.
3
4
IN+
IN-
Noninverted Data Input
Inverted Data Input
5
FAULT
Fault Indicator. Open-drain output with ESD protection. FAULT is asserted high during a
fault condition.
6
SQUELCH
Squelch Enable. Squelch is enabled when the pin is set high. Squelch is disabled when the pin is
set low or left open.

CC
+3.3V Supply Voltage

TC1
Temperature Compensation Set Pin 1. A resistor placed between TC1 and TC2 (R
TC
) programs the
temperature coefficient of the modulation current.
9
TC2
Temperature Compensation Set Pin 2. A resistor placed between TC1 and TC2 (R
TC
) programs the
temperature coefficient of the modulation current.
11
MODSET
Modulation Set. A resistor connected from MODSET to ground (R
MODSET
) sets the desired
modulation current amplitude.
12
PEAKSET
Peaking Current Set. A resistor connected between PEAKSET and ground (R
PEAKSET
) programs the
peaking current amplitude. To disable peaking, leave PEAKSET open.

15
OUT-
OUT+
Inverted Modulation-Current Output
Noninverted Modulation-Current Output
17
BIASSET
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.
18
BIAS
Bias Current Output
19
BIASMON
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.
21
COMP
Compensation Pin. A capacitor between COMP and MD compensates the APC. A typical value of
0.047μF is recommended. For open-loop configuration, short the COMP pin to GND to deactivate
the APC.
22
MD
Monitor Diode Connection
23
REF
Refer ence P n. Refer ence m oni or used for AP C A r esi stor b etw een RE F and M D ( R
P WRS E T
) sets the
p hoto m oni or cur ent w hen the AP C l oop i s cl osed
24
PWRMON
Average Power Monitor. The pin is used to monitor the transmit optical power. For open-loop
configuration, connect PWRMON to GND.
EP
Exposed Pad
Ground. Must be soldered to the circuit board ground for proper thermal and electrical
performance. See the
Layout Considerations
section.
