WARNING

PERSONAL INJURY

DO NOT USE these

products as safety or

emergency stop devices, or

in any other application

where failure of the product

could result in personal

injury.

Failure to comply with

these instructions could

result in death or serious

injury.

The GFD3500-002 is a high-speed optical receiver designed for data

transmission in industrial LAN applications. The monolithic CMOS

(Complementary Metal-Oxide Semiconductor) chip consists of a large area

photodiode, pre-amplifier with controlled gain, a post-amplifier, a comparator

and TTL output stage. The integrated voltage regulator provides easy use in

many applications.

The chip’s silicon material is optimized for 660 nm operation. The on-chip

controlled gain provides a wide dynamic range and low PWD (Pulse Width

Distortion).

The chip is mounted in a metal TO-18 package. This feature allows the

receiver to operate in harsh environments.

The receiver is designed to work with Honeywell’s high-speed 660 nm

transmitter, the HFE7000.

For maximum performance of this receiver, a 0.1 µF capacitor must be

mounted between Vcc and ground no more than 3.0 mm [0.12 in] away from

the housing. A 4.7 Ω resistor in series with Vcc increases the filter’s

performance. This minimizes external noise and allows the maximum

sensitivity to be maintained.

OPERATION

Optical power (photons) from the fiber strikes the

active area of the photodiode and is converted to an

electrical signal. The current is then converted to a

voltage in the transimpedance pre-amplifier. The

controlled gain limits the light current created by the

photodiode in both the transimpedance pre-amplifier

and in the post-amplifier. This avoids a possible

overcharge of the amplifier and assures optimum

PWD performance.

The signal is compared with a threshold defining

the system’s sensitivity limit. A final buffer provides a

TTL output. The level sensitive behavior makes the

system robust with respect to the external

interference (e.g. current/voltage spikes). The

regulator supplies the entire system to ensure high

rejection of power supply noise.
