HFBR-5320Z

HFBR-5320Z 200 MBd RoHS Compliant SBCON Multimode Fiber Transceiver Data Sheet Description The HFBR-5320Z SBCON transceiver from Avago provides system designers with a product to implement a range of solutions compliant with the IBM® Enterprise System Connection (ESCON)® architecture. Transmitter Section The transmitter section of the HFBR-5320Z utilizes 1300 nm Surface Emitting InGaAsP LED. The LED is packaged in an optical sub-assembly within the transmitter section. The LED is driven by a custom silicon IC which converts differential PECL logic signals [ECL referenced (shifted) to a +5 Volt supply] into an analog LED drive current. Receiver Section The receiver section of the HFBR-5320Z utilizes an InGaAs PIN photodiode coupled to a custom silicon transimpedance preamplifier IC. This PIN/preamplifier combination is coupled to a custom quantizer IC which provides the final pulse shaping for the logic Data Output and Status Flag function. The Data and Status Flag Outputs are differential PECL compatible [ECL referenced (shifted) to a +5 Volt power supply] logic outputs. Package The overall package concept for the Avago transceiver consists of the following basic elements: two optical subassemblies, an electrical sub-assembly and the housing with an integral duplex SBCON connector receptacle. This is illustrated in Figure 1. The package outline and pin-out are shown in Figures 2 and 3. The package includes internal shields for the electrical and optical sub-assemblies to ensure low EMI emissions and high immunity to EMI fields.

Block diagram. The optical sub-assemblies utilize a high-volume assembly process together with low-cost lens elements which result in a cost-effective building block. The electrical subassembly consists of a high-volume multi-layer printed circuit board on which the IC circuits and various surface-mount passive circuit elements are attached. The outer housing, including the SBCON-compliant duplex connector receptacle, is molded of filled, non-conductive UL 94V-0 flame retardant Ultem® plastic (U.L. File E121562) to provide mechanical strength and electrical isolation. The transceiver is attached to a printed circuit board with 28 signal pins (4 rows of 7 pins) and with the four slots on the flanges which are located on the package sides. These four slots on the flanges provide the primary mechanical strength to withstand the loads imposed by the duplex connectored fiber cables. Applications Information The Applications Engineering group in the Avago Optical Communications Division is available to assist you with the technical understanding associated with this transceiver. You can contact them through your local Avago sales representative. Avago LED technology has produced 1300 nm LED devices with lower aging characteristics than normally associated with these technologies in the industry. The industry convention is 1.5 dB aging for 1300 nm LEDs. The Avago LED will normally experience less than half this amount of aging over normal, commercial equipment mission-life periods. Contact your local Avago sales representatives for additional details. Recommended Handling Precautions It is advised that normal, anti-static precautions be taken in the handling and assembly of these transceivers to prevent damage which may be induced by electrostatic discharge (ESD). The HFBR-5320Z transceiver meets MilStd-883C Method 3015.4 Class 2. Care should be used to avoid shorting the receiver Data or Status Flag Outputs directly to ground without proper current limiting impedance. Solder and Wash Process Compatibility The transceiver is delivered with a protective process plug inserted into the duplex SBCON connector receptacle. This process plug protects the optical sub-assemblies during wave solder and aqueous wash processing and acts as a dust cover during shipping. These transceivers are compatible with either industry standard wave or hand soldering processes. The process plug part number is HFBR-5002. Shipping Container The transceiver is packaged in a shipping container designed to protect it from mechanical and ESD damage during shipment or storage. Board Layout - Decoupling Circuit and Ground Planes It is important to take care in the layout of your circuit board to achieve optimum performance from the transceiver. Figure 3 provides a good example of a schematic for a power supply decoupling circuit that works well with this part. It is further recommended that a contiguous ground plane be provided in the circuit board directly under the transceiver to provide a low inductive ground for signal return current. This recommendation is in keeping with good high-frequency board layout practices.

See the Regulatory Compliance Table for details. Additional information is available from your local Avago sales representative. Electromagnetic Interference (EMI) Most equipment designs utilizing this high-speed transceiver from Avago will be required to meet the requirements of FCC in the United States, CENELEC EN55022 (CISPR 22) in Europe and VCCI in Japan. Electrostatic Discharge (ESD) There are two design cases in which immunity to ESD damage is important. Immunity The first case is during handling of the transceiver prior to mounting it on the circuit board. It is important to use normal ESD handling precautions for ESD sensitive devices. These precautions include using grounded wrist straps, work benches, and floor mats in ESD controlled areas. The second case to consider is static discharges to the exterior of the equipment chassis containing the transceiver parts. To the extent that the SBCON-compatible duplex connector receptacle is exposed to the outside of the equipment chassis, it may be subject to whatever ESD system level test criteria that the equipment is intended to meet.

This is the maximum voltage that can be applied across the Differential Transmitter Data Inputs to prevent damage to the input ESD protection circuit. 2. The outputs are terminated with 50 Ω connected to VCC –2 V. 3. The power supply current needed to operate the transmitter is provided to differential ECL circuitry. This circuitry maintains a nearly constant current flow from the power supply. Constant current operation helps to prevent unwanted electrical noise from being generated and conducted or emitted to neighboring circuitry. 4. This value is measured with the outputs terminated into 50 Ω connected to VCC –2 V and an Input Optical Power Level of –14.5 dBm average. 5. The power dissipation value is the power dissipated in the receiver itself. Power dissipation is calculated as the sum of the products of supply voltage and currents, minus the sum of the products of the output voltages and currents. 6. This value is measured with respect to VCC with the output terminated into 50 Ω connected to VCC –2 V. 7. The output rise time and fall times are measured between 20% and 80% levels with the output connected to VCC – 2 V through 50 Ω. 8. Eye-width specified defines the minimum clock time-position range, centered around the center of the 5 ns baud interval, at which the BER must be 10–12 or better. Test data pattern is PRBS 27–1. The maximum change in input optical power to open the eye to 1.4 nsec from a closed eye is 1.0 dB. 9. These optical power values are measured with the following conditions: • The Beginning of Life (BOL) to the End of Life (EOL) optical power degradation is assumed to be 1.5 dB per the industry convention for long wavelength LEDs. The actual degradation observed in normal commercial environments will be –36.0 dBm avg., then SF = 1 (high) If Power –36.0 dBm avg. to
