HFD3020-500 Series
The HFD3020-500 provides a noise-immune monolithic optical receiver for fibre-
optical applications in the visible range at 520 nm, 660 nm and 850 nm.
Its fibre-optical receiver (integrated device with small mechanical dimensions) has
been designed for optical data transfer via polymer fibres (POF, fibre type A4a
under IEC 60793-2:1998), HCS fibres (fibre type A3c under IEC 60793-2:1998) and
gradient-index glass fibres. Precisely, it serves to convert light into logic levels
(CMOS) for data rates up to 25 Mb/s NRZ.
The HFD3020-500 consists of these functional groups: Photodiode, Amplifier (trans-
impedance) and Main Amplifier. All functional groups are DC-coupled to allow for
steady light applications of the IC.
An essential advantage over other comparable solutions is the optical dynamic
range from 0dBm to –30dBm in connection with high speed.
Typical Applications.
Data communications
CCTV systems
Machine tools
Controls/drives
Packaging, converting and food
processing machines
Assembly handling and robots
Simulators and test equipment
