ww U.cDESCRIPTION
The HFD3020 is a sensitive differentiating optical
t4receiver designed for use in short distance, 850 nm fiber
optic systems. The receiver uses a hybrid construction
consisting of a PIN photodiode, bipolar integrated
ereceiver circuit with internal voltage regulation and
external bypass capacitor. The TTL output allows the
eHFD3020 to be interfaced directly with standard TTL
circuits. It is supplied in a Honeywell plastic package, and
hcan be mounted in several fiber optic connectors.
Companion optical transmitters are available.
SAPPLICATION
Digital HFD3020 fiber optic receivers convert the optical
signal in a point to point data communications fiber optic
talink to a TTL output. The receiver is designed to be
mounted in a fiber optic connector that aligns the optical
axis of the component to the axis of the optical fiber. Its
aPIN photodiode is mechanically centered within the
TO-18 package.
.DElectrical isolation is important in obtaining the maximum
performance of this high sensitivity receiver. A 0.1 µF
mceramic capacitor must be connected between pin #1
and pin #4. This minimizes external noise on the power
w .coleads. Shielding can reduce coupled noise and allow the
maximum sensitivity to be obtained. This can include the
Uuse of ground planes in the PCB, shielding around the
wdevice, and shielding around the leads. The specified
t4maximum operating temperature of 100¡C allows the
eHFD3020 to be designed into a broad variety of
w eapplications.
