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 Literature 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. 2 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: ______________________________________________________ (If blank, see barcode label) 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.

(0.073) DIMENSIONS IN MILLIMETERS (INCHES). 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. Stacking Horizontal Modules Stacking Vertical Modules Figure 1.

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.

All HFBR-15XX LED transmitters are classified as IEC 825-1 Accessible Emission Limit (AEL) Class 1 based upon the current proposed draft scheduled to go into effect on January 1, 1997. AEL Class 1 LED devices are considered eye safe. Contact your Avago sales representative for more information. Transmitter Electrical/Optical Characteristics 0°C to 70°C unless otherwise specified.

Rise and fall times are measured with a voltage pulse driving the transmitter and a series connected 50 Ω load. A wide bandwidth optical to electrical waveform analyzer, terminated to a 50 Ω input of a wide bandwidth oscilloscope, is used for this response time measurement. 17 HFBR-25X3 Receiver DO NOT CONNECT 5 4 VCC 3 OPEN 2 1 DO NOT CONNECT Pin # 1 2 3 4 5 8 GROUND VO 8 Function VO Ground Open VCC Do not connect Do not connect Note: Pins 5 and 8 are for mounting and retaining purposes only.

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.
