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.
Typical Applications.
Data communications
CCTV systems
Machine tools
Controls/drives
Packaging, converting and food
processing machines
Assembly handling and robots
Simulators and test equipment
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.

25 Mb Direct Coupled Receiver
The HFD3020-500 is a sensitive mixed-signal IC operating at high frequencies. Please note that the case is
connected to the GND pin. Care should be taken applying the IC to meet the specifications. Prototyping boards are
not recommended. A good practice is to use a printed circuit board (PCB) with a ground plane. A 100 nF ceramic
chip capacitor should be placed as close as possible to the power supply pins.
A) This figure shows a simple circuit. In addition to the ceramic capacitor a 10 µF electrolytic capacitor is used for
supply buffering. Tantalum capacitors are a better choice than aluminium parts.
B) This circuit shows a LC filter for better noise suppression. Tantalum capacitors are recommended. Please note
that the HFD3020-500 draws about 35 mA. The inductor resistance should be lower than 1 Ω to avoid large voltage
drops. This filter configuration is useful when noisy power supplies are used.
C) Some applications require buffering or inverting of the output signal. Therefore good supply filtering of the
HFD3020-500 is recommended to suppress peaks caused by the switching of the buffer. A decoupling capacitor
must be applied to the supply of the buffer.
D) Most applications are digital systems (shown as a buffer) where the output data of the HFD3020-500 are
processed using microcontrollers and digital signal processors. It is well known that digital circuits produce much
noise which may disturb the analog parts. Therefore special care must be taken to keep digital noise away from the
receiver. It is proposed to separate the analog power supply (AVDD) from the digital power supply (DVDD) and the
analog ground (AGND) from the digital ground (DGND) as well. Use just one point on the PCB to connect AGND
and DGND. This connection is symbolized by the 0 Ω bridge in the figure. Avoid ground loops. A ground plane for
AGND is recommended.
Power supply filtering is necessary if switched-mode power supplies or switched-mode regulators such as DC-DC
converters are used because of their switching noise. Excessive noise can disturb the performance of the ASIC. An
additional linear regulator for AVDD may help to damp the ripple.
Buffering the HFD3020-500
Some applications require buffering, inverting or level shifting of DOUT. Long wires and cables are not
recommended for interfacing the IC with other circuits. The ASIC is designed to drive a load of 5 pF. Please note
that an additional circuit may reduce the rise and fall times of the IC.
The pulse width at DOUT is measured at 0.5 x VDD and can change at the output of the buffer compared to the
original pulse width at DOUT. This is an additional PWD (pulse width deviation) caused by buffers operating at TTL
levels (or other levels) and can slightly reduce the system performance.
Bus drivers or logic gates of the CMOS standard logic series like 74HC, 74AC, 74LCX or 4K are recommended for
buffering or inverting of DOUT. Connect only one gate or buffer to DOUT. Please check if the rise and fall times are
sufficient for the application.
