HFBR-0500Z Series

Versatile Link The V ersa tile Fiber Optic Connection

Data Sheet

Description

The Versatile Link series is a complete family of fiber optic link components for applications requiring a low cost solution. The HFBR-0500Z 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-0500Z 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 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 available for use in the HFBR-25X1Z/ 2Z/4Z 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

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.

Package Orientation

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

VALOX® is a registered trademark of the General Electric Corporation.

when making connections. Receivers are blue and transmitters 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 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.

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.

CAUTION

This bag contains

MOISTURE-SENSITIVE

DEVICES

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.

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.

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.

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

PCB EDGE

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.

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 t 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.

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-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 filter out signals from this source if they pose a hazard to the system.

4. Including current in 3.3 k pull-up resistor.
