DESCRIPTION The HFD3029-002/XXX is a sensitive Schmitt triggered optical receiver designed for use in short distance, 850 nm fiber optic systems. The bipolar integrated receiver circuit has internal voltage regulation. The HFD3029-002/XXX also uses an internal photodiode. The TTL non-inverting output allows the HFD3029-002/XXX to be directly interfaced with standard digital TTL circuits. APPLICATION The HFD3029-002/XXX fiber optic receiver converts the optical signal in a point to point data communications fiber optic link to a TTL output. It is mounted in a fiber optic connector that aligns the optical axis of the component to the axis of the optical fiber. Electrical isolation is important in obtaining the maximum performance of this high sensitivity receiver. Shielding can reduce coupled noise and allow maximum sensitivity to be obtained. This can include the use of ground planes in the PCB, shielding around the device, and shielding around the leads.

HFD3029-002/XXX
Schmitt Input, Non-Inverting TTL Output Receiver
APPLICATION (continued) An internal voltage regulator allows operation with a 5 volt supply. An external bypass capacitor (0.1 F) between VUU (pin 1) and ground (pin 3) is recommended for maximum power supply noise rejection. Honeywell also offers companion transmitters designed to operate in conjunction with the HFD3029-002/XXX. Optical power (photons) from the fiber strikes the photodiode and is converted to electrical current. The current is converted into voltage in the transimpedance preamplifier. The Schmitt trigger circuitry in the comparator stage provides proper output signals. The Schmitt detection circuit monitors the input preamplifier, and triggers when its output exceeds present levels. Preset levels are above worst case RMS noise level, with 1 x 10ox bit error rate, while low enough for enough sensitivity to allow operation over long links. This circuitry recognizes positive and negative going input signals. When the optical input goes from low to high, the electrical output changes to "1" (high). The output changes to "0" (low) when the optical input goes from high to low. Bandwidth has been limited to minimize noise problems. The output of the Schmitt Trigger detector stage is designed for good pulse width distortion (PWD).

Catalog Listing HFD3029-002/XXX
FIBER INTERFACE Honeywell detectors are designed to interface with multimode fibers with sizes (core/cladding diameters) ranging from 50/125 to 200/230 microns. Honeywell performs final tests using 100/140 micron core fiber. The fiber chosen by the end user will depend upon a number of application issues (distance, link budget, cable attenuation, splice attenuation, and safety margin). The 50/125 and 62.5/125 micron fibers have the advantages of high bandwidth and low cost, making them ideal for higher bandwidth installations. The use of 100/140 and 200/230 micron core fibers results in greater power being coupled by the transmitter, making it easier to splice or connect in bulkhead areas. Optical cables can be purchased from a number of sources.
