The transmitters are easily identifi ed by the light grey color connector port. The receivers are easily identifi ed by the dark grey color connector port. (Black color for conductive port). The package is designed for pick and place and wave soldering so it is ideal for high volume production applications. Handling and Design Information Each part comes with a protective port cap or plug covering the optics. Note: This plastic or rubber port cap is made to protect the optical path during assembly. It is not meant to remain on the part for a long period. These caps/plugs will vary by port style. When soldering, it is advisable to leave the protective cap on the unit to keep the optics clean. Good system performance requires clean port optics and cable ferrules to avoid obstructing the optical path. Clean compressed air often is suffi cient to remove particles of dirt; methanol on a cotton swab also works well. Recommended Chemicals for Cleaning/Degreasing 820 nm Miniature Link Products 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, Broadcom does not recommend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm. Broadcom - 5 -

HFBR-14xxZ and HFBR-24xxZ Series Data Sheet 5 MBaud Logic Link Design The resistor R1 is the only signifi cant element in the drive circuit (see Figure 2) that limits the current through the LED, apart from the gate´s output port. Depending on the actual gate used, the voltage drop on the output port V could be neglected. The port forward voltage value, V , of the LED depends on the desired LED current and on the temperature (see Figure 9). Make sure you F take this behavior into account for the calculations. The curves in Figure 3, Figure 4, and Figure 5 are constructed assuming no inline splice or any additional system loss. Besides fi ber attenuation, for correct power budget calculation, make sure you take into account the eff ect of bending, humidity, ambient temperature, aging and other relevant infl uences. All these additional losses reduce the achievable link distance accordingly. For calculating the LED's aging eff ect, an additional loss of about 1.5 dB is recognized. The following example will illustrate the technique for selecting the appropriate value of I and R1: F R1=VCC -VF IF Maximum distance required = 2000 meters by using HFBR-14x4Z/24x2Z logic link with 62.5/125 μm fi ber. Figure 4 shows the “worst-case” drive current of about 43 mA for reaching a distance of about 2000 meters. Figure 9 shows the transmitter forward voltage of about V = 1.62V. If the typical circuit confi guration (Figure 2) is used at V = 5.0 F cc V, the resistor value “R1” should be choosen to 78.6Ω (3.38 V/43 mA) for reaching driver current of about 43 mA. Page 16 shows the guaranteed HFBR-14x4Z´s optical output power limit of -16.0 dBm (for driver current of 60 mA) over the entire temperature range. Figure 10 shows the normalized typical output power. When the transmitter will be driven with 43 mA the optical output power is about 0.70 or –1.55 dB lower than at 60 mA. With an assumed fi ber attenuation of 3.2 dB/km and the reduced driver current of 43 mA, the minimum optical output power at fi ber end is about –24 dBm, which is equal to the receiver sensitivity over the entire temperature range. For balancing the individual additional system losses, the driver current must be increased accordingly. Figure 2.

Total lead length between both ends of the capacitor and the pins should not exceed 20 mm. The following diagrams (Figure 3 to Figure 5) serve as an aid in Link Design and are based on theoretical calculations. For broad use, no additional eff ects such as aging were taken into account. The additional losses and the individual safety buff er values should be added separately. These diagrams refl ect the pure viewing of power budget and do not allows conclusions about the actual link quality. Overdrive: Maximum optical output power of Tx combined with receiver sensitivity of –10 dBm over the entire temperature range. Typical 25°C: Typical optical output power of Tx combined with receiver sensitivity of –25.4 dBm at T = 25°C.

HFBR-14xxZ and HFBR-24xxZ Series Data Sheet HFBR-24x2Z Low-Cost 5 MBaud Receiver Description The HFBR-24x2Z fi ber optic receiver is designed to operate with the Broadcom Ltd. HFBR-14xxZ fi ber optic transmitter and 50/125 μm, 62.5/125 μm, 100/140 μm, and 200 μm Plastic-Clad Silica (PCS) fi ber optic cable. Consistent coupling into the receiver is assured by the lensed optical system (Figure 1). Response does not vary with fi ber size ≤ 0.100 μm. The HFBR-24x2Z receiver incorporates an integrated photo IC containing a photodetector and dc amplifi er driving an open- collector Schottky output transistor. The HFBR-24x2Z is designed for direct interfacing to popular logic families. The absence of an internal pull-up resistor allows the open-collector output to be used with logic families such as CMOS requiring voltage excursions much higher than V . CC Both the open-collector Data output Pin 6 and V Pin 2 are referenced to Com Pins 3 and 7. The Data output allows busing, CC strobing and wired OR circuit confi gurations. The transmitter is designed to operate from a single +5V supply. It is essential that a bypass capacitor (100 nF ceramic) be connected from Pin 2 (V ) to Pin 3 (circuit common) of the receiver.

The numerical value is the product of the actual detector diameter and the lens magnifi cation. 5. Measured at the end of 100/140 μm fi ber optic cable with large area detector. 6. Propagation delay through the system is the result of several sequentially-occurring phenomena. Consequently it is a combination of data-rate-limiting eff ects and of transmission-time eff ects. Because of this, the data-rate limit of the system must be described in terms of time diff erentials between delays imposed on falling and rising edges. As the cable length is increased, the propagation delays increase at 5 ns per meter of length. Data rate, as limited by pulse width distortion, is not aff ected by increasing cable length if the optical power level at the receiver is maintained. CAUTION: The small junction sizes inherent to the design of these components increase the components’ susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and assembly of these compo- nents to prevent damage and/or degradation which may be induced by ESD. Broadcom - 20 -

HFBR-14xxZ and HFBR-24xxZ Series Data Sheet HFBR-24x6Z Low-Cost 125 MHz Receiver Description The HFBR-24x6Z fi ber optic receiver is designed to operate with the Broadcom Ltd. HFBR-14xxZ fi ber optic transmitters and 50/125 μm, 62.5/125 μm, 100/140 μm, and 200 μm Plastic-Clad Silica (PCS) fi ber optic cable. Consistent coupling into the receiver is assured by the lensed optical system (Figure 1). Response does not vary with fi ber size for core diameters of 100 μm or less. The receiver output is an analog signal which allows follow-on circuitry to be optimized for a variety of distance/data rate requirements. Low-cost external components can be used to convert the analog output to logic compatible signal levels for various data formats and data rates up to 175 MBaud. This distance/data rate trade-off results in increased optical power budget at lower data rates which can be used for additional distance or splices. The HFBR-24x6Z receiver contains a PIN photodiode and low noise transimpedance preamplifi er integrated circuit. The HFBR- 24x6Z receives an optical signal and converts it to an analog voltage. The output is a buff ered emitter follower. Because the signal amplitude from the HFBR-24x6Z receiver is much larger than from a simple PIN photodiode, it is less susceptible to EMI, especially at high signaling rates. For very noisy environments, the conductive or metal port option is recommended. A receiver dynamic range of 23 dB over temperature is achievable, assuming a Bit Error Rate (BER) of 10-9. The frequency response is typically DC to 125 MHz. Although the HFBR-24x6Z is an analog receiver, it is compatible with digital systems. The recommended ac coupled receiver circuit is shown in Figure 14. A 10Ω resistor must be connected between pin 6 and the power supply, and a 100 nF ceramic bypass capacitor must be connected between the power supply and ground. In addition, pin 6 should be fi ltered to protect the receiver from noisy host systems. Refer to AN 1065 for details.
