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. Low cost fiber optic components 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. Flame retardant 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. Enhanced digital links DC -5 MBd Extended distance links up to 120 m at 40 kBd Low current link: 6 mA peak supply current Horizontal and vertical mounting Interlocking feature High noise immunity Easy connectoring Simplex, Duplex, and Latching connectors Transmitters incorporate a 660 nm Red LED for easy visibility Compatible with standard TTL circuitry Applications Reduction of lightning/voltage transient susceptibility Motor controller triggering Data communications and local area networks Electromagnetic Compatibility (EMC) for regulated systems: FCC, VDE, CSA, etc. Tempest-secure data processing equipment Isolation in test and measurement instruments Error free signalling for industrial and manufacturing equipment Automotive communications and control networks Noise immune communication in audio and video equipment HFBR-0501 Series Part Number Guide HFBR X5XX 1 = Transmitter 2 = Receiver 5 = 600 nm Transmitter and Receiver Products 1 = 5 MBd High Performance Link 2 = 1 MBd High Performance Link 3 = 40 kBd Low Current/Extended Distance Link 4 = 1 MBd Standard Link 6 = 155 MBd Receiver 7 = 155 MBd Transmitter 8 = 10 MBd High Performance Link 2 = Horizontal Package 3 = Vertical Package Link Selection Guide (Links specified from 0 to 70 C, for plastic optical fiber unless specified.)

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. Application Note 1035 (Versatile Link) Package Housing Color Package and Handling Information 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. This kit contains: HFBR-1524 Tx, HFBR-2524 Rx, polishing kit, 3 styles of plastic connectors, Bulkhead feedthrough, 5 meters of 1 mm diameter plastic cable, lapping film and grit paper, and HFBR-0501 data sheet. 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. 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. 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. 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. CAUTION Level This bag contains MOISTURE-SENSITIVE DEVICES 4 1. Shelf life in sealed bag: 12 months at < 40C 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 30C/60% RH. b) Stored at 20% RH. 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.

(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.

Rise and fall times are measured with a voltage pulse driving the transmitter and a series connected 50 load. A wide bandwidth optical to electrical waveform analyzer, terminated to a 50 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 GROUND VO 8 Pin # Function 1 VO 2 Ground 3 Open 4 VCC 5 Do not connect 8 Do not connect Note: Pins 5 and 8 are for mounting and retaining purposes only.

Measured at the end of the fiber optic cable with large area detector. 2. Optical flux, 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 filter out signals from this source if they pose a hazard to the system. 4. Including current in 3.3 k pull-up resistor.
