WARNING
PERSONAL INJURY
DO NOT USE these products as
safety or emergency stop
devices, or in any other applica-
tion where failure of the product
could result in personal injury.
Failure to comply with these
instructions could result in
death or serious injury.
NOTICE
Stress greater than those listed
under “Absolute Maximum
Ratings” may cause permanent
damage to the device. This is a
stress rating only and functional
operation of the device at these
or any other conditions above
those indicated in the opera-
tional section of this specification
is not implied. Exposure to
absolute maximum rating
conditions for extended periods
of time may affect reliability.

DESCRIPTION
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 applica-
tions.
The chip’s silicon material is optimized for 660 nm operation. The
on-chip controlled gain provides a wide dynamic 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, HFE 7000.
TYPICAL APPLICATIONS
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 resistor in series with Vcc increases
the filter’s performance. This minimizes external noise and allows the
maximum sensitivity to be obtained.

OPERATION
Optical power (photons) from the fiber strikes the
active area of the photodiode and is then 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.
www.DataSheet4TUh.ceomsignal is compared with a threshold defining
the system’s sensitivity limit. A final buffer provides
TTL output. The level-sensitive behavior makes the
system robust with respect to external interference
(e.g. current/voltage spikes). The regulator supplies
the entire system to ensure high rejection to power
supply noise.
