HFD3023-500 Series Fiber Optic TTL Detector Fiber Optic Components The HFD3023-500 Series is a direct coupled optical receiver designed for use in short distance 850 nm fiber optic systems. The receiver contains a monolithic IC Integrated Circuit with an integral photodiode and amplification circuit, and an open collector Schottky output. The output allows it to be directly interfaced with standard TTL Transistor-Transistor Logic circuits. The HFD3023-500 Series converts the optical signal in a pointto-point data communications fiber optic link to a TTL output. The in photodiode with a in microlens to enhance the optics is mechanically centered within the TO46 package. Electrical isolation is important in obtaining the maximum performance. A µF bypass capacitor must be connected between Vcc 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. Optical power from the fiber strikes the photodiode and is converted to electrical current. This current couples to the dc amplifier, which drives an open collector transistor output. The output, when connected to a pull up resistor, can interface to TTL loads. The electrical signal is the inverse of the input light signal. When light strikes the photodiode, the output is a low logic level. When no light strikes the photodiode, the output is a high logic level.

The typical performance curves illustrate how PWD varies with optical power, temperature and frequency. The amount of PWD that a given system can tolerate without an error due to a missing bit of information is dependent upon system considerations. The output of the HFD3023 will typically connect to the input of some form of a serial interface adaptor IC. The specifications for that IC govern the amount of PWD that can be tolerated in the system. The HFD3023-500 Series is the suggested replacement for Honeywell’s HFD3023-002 Series.

The receiver contains a monolithic IC Integrated Circuit with an integral photodiode and amplification circuit, and an open collector Schottky output.

The HFD3023-500 Series converts the optical signal in a pointto-point data communications fiber optic link to a TTL output. The in photodiode with a in microlens to enhance the optics is mechanically centered within the TO46 package.
