Description
The Versatile Link series is a complete family of ber optic
link components for applications requiring a low cost
solution. The HFBR-0501 series includes transmitters,
receivers, connec tors and cable speci ed for easy design.
This series of compo nents is ideal for solving problems
with voltage isolation/insula tion, EMI/RFI immunity or
data security. The optical link design is simpli ed by the
logic compat ible receivers and complete speci cations
for each component. The key optical and electrical para-
meters of links con gured with the HFBR-0501 family are
fully guaranteed from 0° to 70° C.
A wide variety of package con g u ra tions and connectors
provide the designer with numerous mechanical
solutions to meet application requirements. The trans-
mitter and receiver compo nents have been designed for
use in high volume/low cost assembly processes such as
auto insertion and wave soldering.
Transmitters incorporate a 660 nm LED. Receivers include
a monolithic DC coupled, digital IC receiver with open
collector Schottky output transistor. An internal pullup
resistor is avail able for use in the HFBR-25X1/2/4 receivers.
A shield has been integrated into the receiver IC to provide
additional, localized noise immunity.
Internal optics have been optim ized for use with 1 mm
diameter plastic optical ber. Versatile Link speci ca-
tions incorporate all connector interface losses. Therefore,
optical calculations for common link applications are
simpli ed.

Package and Handling Information
The compact Versatile Link pack age is made of a ame
retardant VALOX UL 94 V-0 material (UL le # E121562)
and uses the same pad layout as a standard, eight pin
dual-in-line package. Vertical and horizontal mountable
parts are available. These low pro le Versa tile Link pack-
ages are stackable and are enclosed to provide a dust
resistant seal. Snap action simplex, simplex latching,
duplex, and duplex latching connectors are o ered with
simplex or duplex cables.
VALOX is a registered trademark of the General Electric Corporation.

Package Orientation
Performance and pinouts for the vertical and horizontal
packages are identical. To provide addi tional attach-
ment support for the vertical Versatile Link housing, the
designer has the option of using a self-tapping screw
through a printed circuit board into a mounting hole at
the bottom of the package. For most applications this is
not necessary.
Package Housing Color
Versatile Link components and simplex connectors are
color coded to eliminate confusion when making connec-
tions. Receivers are blue and transmit ters are gray, except
for the HFBR-15X3 transmitter, which is black.

Handling
Versatile Link components are auto-insertable. When
wave soldering is performed with Versatile Link compo-
nents, the optical port plug should be left in to prevent
contamination of the port. Do not use re ow solder
processes (i.e., infrared re ow or vapor-phase re ow).
Nonhalogenated water soluble uxes (i.e., 0% chloride),
not rosin based uxes, are recom mended for use with
Versatile Link components.
Versatile Link components are moisture sensitive devices
and are shipped in a moisture sealed bag. If the compo-
nents are exposed to air for an extended period of time,
they may require a baking step before the solder ing
process. Refer to the special labeling on the shipping tube
for details.

Recommended Chemicals for Cleaning/Degreasing
Alcohols: methyl, isopropyl, isobutyl.
Aliphatics: hexane, heptane.
Other: soap solution, naphtha.
Do not use partially halogenated hydrocarbons such
as 1,1.1 trichloroethane, ketones such as MEK, acetone,
chloroform, ethyl acetate, methylene dichloride, phenol,
methylene chloride, or N-methylpyrolldone. Also, Avago
does not recommend the use of cleaners that use halo-
genated hydrocarbons because of their potential environ-
mental harm.

Horizontal Module Vertical Module
Interlocked (Stacked) Assemblies (refer to Figure 1)
Horizontal packages may be stacked by placing units
with pins facing upward. Initially engage the inter -
locking mechanism by sliding the L bracket body from
above into the L slot body of the lower package. Use a
straight edge, such as a ruler, to bring all stacked units
into uniform alignment. This tech nique prevents potential
harm that could occur to ngers and hands of assem-
blers from the package pins. Stacked horizontal packages
can be disengaged if necessary. Repeated stacking and
unstack ing causes no damage to individual units.
To stack vertical packages, hold one unit in each hand,
with the pins facing away and the optical ports on the
bottom. Slide the L bracket unit into the L slot unit. The
straight edge used for horizontal package alignment is
not needed.

Notes:
1. For IFPK > 80 mA, the duty factor must be such as to keep IFdc ≤80 mA. In addition, for IFPK > 80 mA, the following rules for pulse width apply:
I
FPK ≤160 mA: Pulse width ≤1 ms
I
FPK > 160 mA: Pulse width ≤1 S, period ≥20 S.
2. The propagation delay for one meter of cable is typically 5 ns.
3. Estimated typical link life expectancy at 40° C exceeds 10 years at 60 mA.
4. Pulsed LED operation at IFPK > 80 mA will cause increased link tPLH propagation delay time. This extended tPLH time contributes to increased pulse

Notes:
1. Measured at the end of the ber optic cable with large area detector.
2. Pulsed LED operation at IF > 80 mA will cause increased link tPLH propagation delay time. This extended tPLH time contributes to increased pulse
width distortion of the receiver output signal.
3. The LED drive circuit of Figure 11 is required for 1 MBd operation of the HFBR-25X2/25X4.
4. Optical ux, P (dBm) = 10 Log [P(W)/1000 W].

3. Because of the very high sensitivity of the HFBR-25X3, the digital output may switch in response to ambient light levels when a cable is not
occupying the receiver optical port. The designer should take care to lter out signals from this source if they pose a hazard to the system.
