AVAGO HFBR-2523

HFBR-0501 Series
Versatile Link
The Versatile Fiber Optic Connection
Data Sheet
Description
Features
The Versatile Link series is a complete family of fiber
optic link components for applications requiring a low
cost solution. The HFBR-0501 series includes
transmitters, receivers, connectors and cable specified
for easy design. This series of components is ideal for
solving problems with voltage isolation/insulation,
EMI/RFI immunity or data security. The optical link design
is simplified by the logic compatible receivers and
complete specifications for each component. The key
optical and electrical parameters of links configured with
the HFBR-0501 family are fully guaranteed from 0° to
70°C.

A wide variety of package configurations and connectors
provide the designer with numerous mechanical solutions
to meet application requirements. The transmitter and
receiver components 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 available 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 optimized for use with 1 mm
diameter plastic optical fiber. Versatile Link specifications
incorporate all connector interface losses. Therefore,
optical calculations for common link applications are
simplified.

Application Note 1035 (Versatile Link)
Package and Handling Information
Package Orientation
The compact Versatile Link package is made of a flame
retardant VALOX® UL 94 V-0 material (UL file # 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 profile Versatile Link
packages are stackable and are enclosed to provide a
dust resistant seal. Snap action simplex, simplex
latching, duplex, and duplex latching connectors are
offered with simplex or duplex cables.
Performance and pinouts for the vertical and horizontal
packages are identical. To provide additional 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
connections. Receivers are blue and transmitters are
gray, except for the HFBR-15X3 transmitter, which is
black.
VALOX® is a registered trademark of the General Electric Corporation.

Handling
Recommended Chemicals for Cleaning/Degreasing
Versatile Link components are auto-insertable. When
wave soldering is performed with Versatile Link
components, the optical port plug should be left in to
prevent contamination of the port. Do not use reflow
solder processes (i.e., infrared reflow or vapor-phase
reflow). Nonhalogenated water soluble fluxes
(i.e., 0% chloride), not rosin based fluxes, are recommended for use with Versatile Link components.
Alcohols: methyl, isopropyl, isobutyl. Aliphatics: hexane,
heptane, Other: soap solution, naphtha.
CAUTION
This bag contains
MOISTURE-SENSITIVE
DEVICES
Level
4
1. Shelf life in sealed bag: 12 months at < 40°C and < 90% Relative
Humidity (RH).
2. After this bag is opened, devices that will be subjected to wave
soldering, or equivalent processing (solder temperature < 260°C for
10 sec) must be:
a) Mounted within 72 hours at factory conditions of ≤ 30°C/60% RH.
b) Stored at ≤ 20% RH.
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
soldering process. Refer to the special labeling on the
shipping tube for details.
3. Devices require baking, before mounting, if:
a) Desiccant changes to PINK.
b) If 2a or 2b are not met.
4. If baking is required, devices may be baked outside of tube for 20
hours at 75°C.
Bag Seal Date: ______________________________________________________

Note: LEVEL defined by EIA JEDEC Standard J-STD-020
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.

Interlocked (Stacked) Assemblies (refer to Figure 1)
Horizontal packages may be stacked by placing units
with pins facing upward. Initially engage the interlocking 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 technique prevents
potential harm that could occur to fingers and hands of
assemblers from the package pins. Stacked horizontal
packages can be disengaged if necessary. Repeated
stacking and unstacking 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.

electrical waveform analyzer, terminated to a 50 Ω input of a wide bandwidth oscilloscope, is used for this response time measurement.

Notes:
1. Measured at the end of the fiber 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 flux, P (dBm) = 10 Log [P(µW)/1000 µW].

Notes:
1. Measured at the end of the fiber optic cable with large area detector.
2. Optical flux, P (dBm) = 10 Log P(µW)/1000 µW.
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 filter out signals from this source if they pose a hazard to the system.
4. Including current in 3.3 k pull-up resistor.
