w U.cDESCRIPTION
The HFD3023 is a sensitive Direct Coupled (DC) optical
t4receiver 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
ecollector Schottky output transistor. The output allows it
to be directly interfaced with standard TTL circuits. The
eHFD3023 receiver is supplied in a Honeywell plastic
package, and can be mounted in several types of fiber
hoptic connectors.
APPLICATION
SThe HFD3023 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
tain. microlens (to enhance the optics) is mechanically
centered within the TO-18 package.
Electrical isolation is important in obtaining the maximum
aperformance. A 0.1 µF bypass capacitor must be
connected between VÙÙ and ground. This minimizes
.Dpower supply noise, increasing the signal quality.
Shielding can also reduce coupled noise, through use of
mground plane PCB, shielding around the device, and
shielding around the leads.
w .coThe HFD3023 is designed for a wide optical input range.
The optical input dynamic range is guaranteed from the
Umaximum sensitivity of 3.0 µW to 100 µW or greater than
w t415 dB.
