Pin Descriptions
Pins 5, 17, 18, 19, 20 NC:
These pins are not connected and should be left open
circuit on the application PCB.
Pins 1, 2, 3, 4, 6, 8, 13, 15, 16 GND:
These pins should be connected to the circuit ground.
Pins 7, 9, DATA, DATA:
These pins provide complementary PECL DATA and DATA
outputs. The DATA output is non inverting, an optical pulse
causes the DATA output to go to the PECL logic high state
(+4 V nominal).
Pin 10, PD Bias:
This pin must be connec ted to any voltage
from 0 V (GND) to -6 V. This provides the photo-
diode bias. The current drawn is directly propor-
tional to the average received photocurrent
I = Responsivity x Mean Power. The responsivity will be
between 0.7 A/W and 1.0 A/W.

Pin 11, +5 V:
This pin should be connected to +5 V supply. The network
shown below should be placed as close as possible to Pin
11.
Pins 12,14 ALARM, ALARM:
These pins provide complementary differential ALARM
and ALARM outputs. This is the low light alarm. ALARM
goes to a logic low (3.3 V nominal) state when the optical
power drops below the threshold level (insufficient optical
power).
The optical power must increase to a higher level than the
level where the alarm went low before ALARM will return
to a logic high. This difference is the alarm hysteresis.
