Pin Descriptions
Pins 1, 3, 10, 20, NC:
These pins should not be con-
nected and should be left open
circuit on the application PCB.
Pin 2, Laser Bias Monitor (+):
See Figure 1.
Pin 4, Laser Bias Monitor (–):
See Figure 1.
Pins 5, 14, V
These pins are connected to
ground in +5 V systems and –5 V
in negative supply systems.

Pins 6, 8, 9, 12, 18, V
These pins are connected to +5 V
for positive supply systems and
ground for –5.2 V systems.
Pin 7, Transmit Disable:
Pin 7 floats to V
circuited, enabling the
transmitter. It must be biased
within 3 V of V
Pins 11, 13, Ground:
The XMT5170-622 case is plastic,
therefore pins are not connected.
