Product Overview

The HFD3023-500 is a fibre optic TTL Detector/direct coupled Optical Receiver designed for use in short distance 850nm fibre optic systems. The receiver contains a monolithic IC with an integral photodiode and amplification circuit and an open collector Schottky output. The output allows it to be directly interfaced with standard TTL circuits. Electrical isolation is important in obtaining the maximum performance. A 0.1µF 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 fibre strikes the photodiode and is converted to electrical current. 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.
  • Converts optical signal in a point-to-point data communications fibre optic link to a TTL output
  • 2µW of typical sensitivity
  • High reliability
  • Integral micro lens for efficient fibre coupling
