UDESCRIPTION
The HFD3029 is a sensitive Schmitt triggered optical
t4receiver designed for use in short distance, 850 nm fiber
optic systems. The bipolar integrated receiver circuit has
internal voltage regulation. The HFD3029 also uses an
einternal photodiode. The TTL non-inverting output allows
the HFD3029 to be directly interfaced with standard
edigital TTL circuits.
APPLICATION
hThe HFD3029 fiber optic receiver converts the optical
signal in a point to point data communications fiber optic
Slink to a TTL output. It 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 photodiode
tais mechanically centered within the TO-18 package.
Electrical isolation is important in obtaining the maximum
performance of this high sensitivity receiver. Shielding
acan reduce coupled noise and allow maximum sensitivity
to be obtained. This can include the use of ground planes
.Din the PCB, shielding around the device, and shielding
around the leads.
mAn internal voltage regulator allows operation with a 5
ovolt supply. An external bypass capacitor (0.1 µF)
w .cbetween VÙÙ (pin 1) and ground (pin 3) is recommended
w Ufor maximum power supply noise rejection.
