DESCRIPTION
The HFD3023-002/XXX is a sensitive Direct Coupled
(DC) optical receiver designed for use in short distance,
850 nm fiber optic systems. The receiver contains a
monolithic IC, consisting of a photodiode, DC amplifier,
and open collector Schottky output transistor. The output
allows it to be directly interfaced with standard TTL
circuits. The HFD3023-002/XXX receiver is comprised of
a HFD3023 receiver component packaged in a fiber optic
connector.
APPLICATION
The HFD3023-002/XXX fiber optic receiver converts the
optical signal in a point to point data communications
fiber optic link to a TTL output. Its 0.006 in. photodiode
with a 0.024 in. microlens (to enhance the optics) is
mechanically centered within the fiber optic connector.
Electrical isolation is important in obtaining the maximum
performance. A 0.1 µF bypass capacitor must be
connected between VÙÙ and ground. This minimizes
power supply noise, increasing the signal quality.
Shielding can also reduce coupled noise, through use of
ground plane PCB, shielding around the device, and
shielding around the leads.
The HFD3023-002/XXX is designed for a wide optical
input range. The optical input dynamic range is
guaranteed from the maximum sensitivity of 3.0 µW to
100 µW or greater than 15 dB.
Honeywell reserves the right to make
changes in order to improve design and
supply the best products possible.
