2 package and handling instructions flammability the HFBR-53A5VEMZ/fmz transceiver housing is made of high strength, heat resistant, chemically resistant, and ul 94v - 0 fame retardant plastic. recommended solder and wash process the HFBR-53A5VEMZ/fmz is compatible with industry- standard wave or hand solder processes. process plug this transceiver is supplied with a process plug (hfbr-5000) for protection of the optical ports within the duplex sc connector receptacle. this process plug prevents contamination during wave solder and aqueous rinse as well as during handling, shipping and storage. it is made of a high-temperature, molded sealing material that can withstand 80c and a rinse pressure of 110 lbs per square inch. recommended solder fluxes solder fluxes used with the HFBR-53A5VEMZ/fmz should be water-soluble, organic fuxes. recom mended solder fluxes include lonco 3355-11 from london chemical west, inc. of burbank, ca, and 100 flux from alpha-metals of jersey city, nj. recommended cleaning/degrading chemicals 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, ac - etone, 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. regulatory compliance (see the regulatory compliance table for transceiver performance) the overall equipment design will determine the certification level. the transceiver performance is ofered as a fgure of merit to assist the designer in considering their use in equipment designs. electrostatic discharge (esd) there are two design cases in which immunity to esd damage is important. the frst 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 pre cautions include using grounded wrist straps, work benches, and floor mats in esd controlled areas. the transceiver perform ance has been shown to provide adequate performance in typical industry production environments. the second case to consider is static discharges to the exterior of the equipment chassis containing the transceiver parts. to the extent that the duplex sc connector receptacle is exposed to the outside of the equipment chassis it may be subject to whatever system-level esd test criteria that the equipment is intend - ed to meet. the transceiver performance is more robust than typical industry equipment requirements of today. electromagnetic interference (emi) most equipment designs utilizing these high-speed transceivers 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. refer to emi section (page 4) for more details. immunity equipment utilizing these transceivers will be subject to radio-frequency electromagnetic felds in some en - vironments. these transceivers have good immunity to such felds due to their shielded design. eye safety these laser-based transceivers are classifed as ael class i (u.s. 21 cfr(j) and ael class 1 per en 60825-1 (+a11). they are eye safe when used within the data sheet limits per cdrh. they are also eye safe under nor - mal operating conditions and under all reasonably forseeable single fault conditions per en60825-1. avago has tested the transceiver design for com - pliance with the requirements listed below under normal operating conditions and under single fault conditions where applicable. tuv rheinland has granted certifcation to these transceivers for laser eye safety and use in en 60950 and en 60825-2 applications. their performance enables the transceivers to be used without concern for eye safety up to maximum volts transmitter v cc .

4 eye safety circuit for an optical transmitter device to be eye-safe in the event of a single fault failure, the trans mit ter must either maintain normal, eye-safe operation or be disabled. in the HFBR-53A5VEMZ/fmz there are three key elements to the laser driver safety circuitry: a monitor diode, a window detec tor circuit, and direct control of the laser bias. the window detection circuit monitors the average optical power using the monitor diode. if a fault occurs such that the transmitter dc regulation circuit cannot maintain the preset bias conditions for the laser emitter within 20%, the transmitter will automatically be disabled. once this has occurred, only an electrical power reset will allow an attempted turn-on of the transmitter. signal detect the signal detect circuit provides a deasserted output signal that implies the link is open or the transmitter is off as defned by the gigabit ethernet specifcation ieee 802.3z, table 38.1. the signal detect threshold is set to transition from a high to low state between the minimum receiver input optional power and C30 dbm avg. input optical power indicating a defnite optical fault (e.g., unplugged connector for the receiver or transmitter, broken fber, or failed far-end transmitter or data source). a signal detect indicating a working link is functional when receiving encoded 8b/10b characters. the signal detect does not detect receiver data error or error-rate. data errors are determined by signal processing following the transceiver. electromagnetic interference (emi) one of a circuit board designers foremost concerns is the control of electromagnetic emissions from elec - tronic equipment. success in controlling gener - ated electromagnetic interference (emi) enables the designer to pass a governmental agencys emi regulatory standard; and more importantly, it reduces the possibility of interference to neighboring equipment. the emi performance of an enclosure using these transceivers is dependent on the chassis design. avago encourages using standard rf suppression practices and avoiding poorly emi-sealed enclosures. application support optical power budget and link penalties the worst-case optical power budget (opb) in db for a fber-optic link is determined by the diference be - tween the minimum transmitter output optical power (dbm avg) and the lowest receiver sensitivity (dbm avg). this opb provides the necessary optical signal range to establish a working fber-optic link. the opb is allocated for the fiber-optic cable length and the corre sponding link penalties. for proper link performance, all penalties that affect the link performance must be accounted for within the link optical power budget. the gigabit ethernet ieee 802.3z standard identifes, and has modeled, the contributions of these opb penalties to establish the link length requirements for 62.5/125 m and 50/125 m multimode fiber usage. refer to the ieee 802.3z standard and its supplemental documents that develop the model, empirical results and fnal specifcations. data line interconnections avagos HFBR-53A5VEMZ/fmz fber-optic transceiver is designed for compatible pecl signals. the transmit - ter inputs are internally ac-coupled to the laser driver circuit from the transmitter input pins (pins 7, 8). the transmitter driver circuit for the laser light source is an ac-coupled circuit. this circuit regulates the output optical power. the regulated light output will maintain a constant output optical power provided the data pattern is reasonably balanced in duty factor. if the data duty factor has long, con tinu ous state times (low or high data duty factor), then the output optical power will gradually change its average output optical power level to its pre-set value. the receiver section is internally ac-coupled between the pre-amplifer and the post-amplifer stages. the actual data and data-bar outputs of the post-amplifer are ac-coupled to their respective output pins (pins 2, 3). signal detect is a single-ended, ttl output signal that is dc-coupled to pin 4 of the module. signal detect should not be ac-coupled externally to the follow-on circuits because of its infrequent state changes. caution should be taken to account for the proper intercon nec tion between the supporting physical layer integrated circuits and this HFBR-53A5VEMZ/ fmz transceiver. figure 3 illustrates a recommended interface circuit for interconnecting to a dc pecl compatible fber-optic transceiver.
