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 complemen-
tary PECL DATA and DATA
outputs. The DATA output is
noninverting, 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 connected to
any voltage from 0 V (GND) to
-5 V. This provides the
photodiode bias. The current
drawn is directly proportional
to the average received
photocurrent.
I = Responsitivity 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 complemen-
tary 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.
