Description
The Versatile Link series is a complete family of ber
optic link components for applications requiring a low
cost solution. The HFBR-0500Z series includes trans-
mitters, 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 parameters of links congured
with the HFBR-0500Z 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 transmitter and
receiver compo nents have been designed for use in high
volume/low cost assembly processes such as auto inser-
tion 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-25X1Z/2Z/4Z receivers. A shield has been in-
tegrated 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cations
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.
Package Orientation
Performance and pinouts for the vertical and hori-
zontal packages are identical. To provide addi tional
attachment 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-15X3Z 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
components 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
halogenated hydrocarbons because of their potential
environmental harm.

Versatile Link Printed Board Layout Dimensions
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
assemblers 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:
IFPK ≤160 mA: Pulse width ≤1 ms
IFPK > 160 mA: Pulse width ≤1 µS, period ≥20 µS.
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 width distortion of the receiver output signal.

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-25X2Z/25X4Z.

HFBR-15X3Z Transmitter
All HFBR-15XXZ LED transmitters are classied as IEC 825-1 Accessible Emission Limit (AEL) Class 1 based upon the current proposed
draft scheduled to go into eect on January 1, 1997. AEL Class 1 LED devices are considered eye safe. Contact your Avago sales
representative for more information.

3. Because of the very high sensitivity of the HFBR-25X3Z, 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.
