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 HFD7000 Series are high-speed optical receivers designed for data
transmission in industrial LAN applications. The monolithic CMOS 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 dyanmic range and low pulse width distortion
(PWD).
The chip is mounted in a metal TO-18 package. In addition, the outer
package of the HFD7000-202 has a metal barrel for high mechanical stability
and excellent shielding against RFI/EMI and ESD. 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 HFE 7000.
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.
