AFBR-16xxZ and AFBR-26x4Z/25x9Z DC-50MBd Versatile Link Fiber Optic Transmitter and Receiver for 1 mm POF and 200 m PCS Data Sheet Description Features The AFBR-16xxZ transmitter utilizes a 650 nm LED source with integrated optics and driver IC for efficient coupling into 1 mm Polymer Optical Fiber (POF). The AFBR26x4Z/25x9Z receiver consists of an IC with an integrated photodiode to produce a logic compatible output. The transmitter input and receiver output are compatible with TTL logic families. The pair operates any type of signal from DC up to 50 MBd at distances up to 50 m with 1 mm POF, up to 200 m at 10 MBd and 120 m at 50 MBd with 200 m Plastic-Clad Silica (PCS), respectively. RoHS-compliant The transmitter is a 3-pin and the receiver is a 4-pin device, packed in Versatile Link housing. Versatile Link components can be interlocked (N-plexed together) to minimize space and to provide dual connections with the duplex connectors. Various simplex and duplex connectors, as well as POF cables are available for Versatile Link components.

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. Package and Handling Information The compact Versatile Link package is made of a flameretardant material and uses the same pad layout as a standard, eight-pin dual-in-line package. Horizontal, Vertical, and Tilted (30) packages 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 horizontal, vertical, and tilted (30) packages are identical. To provide additional attachment support for the vertical Versatile Link housing, the designer has the option of using a selftapping 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. Receiver packages are black and transmitter packages are gray in color respectively. 2 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. 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.

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 Tilted (30) Module Figure 1.

Its input data is compatible with TTL logic level. This transmitter can operate from DC to 50 MBd with any kind of data pattern using 1 mm Polymer Optical Fiber (POF).

For any type of data between DC and 50 Mbd. Typical value 21 mA for PRBS-7 pattern at 25 C at 5 V and 50 Mbaud. 2. Standard TTL compatible input. 3. Measured with polished connector end face: after 1 meter 1 mm POF, NA = 0.5, or 200 m PCS, NA = 0.37. 4. Pulse width is measured at 50% threshold using a rising edge trigger tested with PRBS-7 pattern 5. Electrical input pulse width is determined at 1.5 V and dU/dt between 1 V and 2 V shall not be less than 1 V/ns. 6. The first pulse is shorter as the LED is completely discharged. This helps to mitigate the increase of pulse width of the first pulse of the Receiver 9 AFBR-26x4Z/25x9Z Receiver The AFBR-26x4Z/25x9Z receiver consists of a digitalizing IC with integrated photodiode to produce an output level that is compatible with TTL logic. The integrated photodiode and the following amplifier uses a fully differential approach with an active and a passive area for an improved EMI performance. Within the specified ranges AFBR-25x9Z and AFBR26x4Z devices will support a BER <10E-9.

Standard TTL output. 2. Measured with RL = 50 k and CL = 15 pF 3. Guaranteed only if optical input signal to the receiver is generated by AFBR-16xxZ, with ideal alignment to photo diode using 1mm POF (NA=0.5). 6. Optical input signal of 50 MBd, PRBS 27 -1 pattern and 50% duty cycle. 7. Pulse width is measured at 50% threshold using a rising edge trigger and PRBS 27-1 pattern. 8. If data rate is below 1MBd the pulse width distortion would be equal to the pulse width distortion of the 1st to 3rd pulses for higher datarates. 9. The threshold of the 1st pulse of a data sequence is difficult to adjust and therefore the pulse width distortion up to the 3rd pulse is higher than for all other pulses (worst case for the 1st pulse). This strongly depends on the quality of the rising and falling edge of the optical input. The faster the edges the smaller the pulse width variation. Furthermore lower data rates would result in the same issue as all the pulse become 1st pulses. 10. Output low for AFBR-26x4Z and Output high for AFBR-25x9Z. 11. Because of optical pulse width spreading, the PWD limits have to be increased by 0.1 ns for each 10 m fiber length. 12. Starting point is when supply voltage passes ~2.8 V.
