2 package and handling instructions flammability the hfct-53d5 transceiver housing is made of high strength, heat resistant, chemically resistant, and ul 94v-0 flame retardant plastic. recommended solder and wash process the hfct-53d5 is compatible with industrystandard 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 hfct-53d5 should be water-soluble, organic fluxes. recommended 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/degreasing 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, acetone, chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride, or n-methylpyrolldone. also, avago technologies 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 offered as a figure 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 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 transceiver performance 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 intended 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 technologies 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 5) for more details. immunity equipment utilizing these transceivers will be subject to radio-frequency electromagnetic fields in some environments. these transceivers have good immunity to such fields due to their shielded design. eye safety these laser-based transceivers are classified 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 normal operating conditions and under all reasonably forseeable single fault conditions per en60825- 1. avago technologies has tested the transceiver design for compliance with the requirements listed below under normal operating conditions and under single fault conditions where applicable. tuv rheinland has granted certification 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 7 volts transmitter vcc.
3 caution: there are no user serviceable parts nor any maintenance required for the hfct-53d5. all adjustments are made at the factory before shipment to our customers. tampering with or modifying the performance of the hfct-53d5 will result in voided product warranty. it may also result in improper operation of the hfct- 53d5 circuitry, and possible overstress of the laser source. device degradation or product failure may result. connection of the hfct-53d5 to a nonapproved optical source, operating above the recommended absolute maximum conditions or operating the hfct-53d5 in a manner inconsistent with its design and function may result in hazardous radiation exposure and may be considered an act of modifying or manufacturing a laser product. the person(s) performing such an act is required by law to recertify and reidentify the laser product under the provisions of u.s. 21 cfr (subchapter j). regulatory compliance feature test method performance electrostatic discharge (esd) to the electrical pins mil-std-883c method 3015.7 class 1 (>2000v). electrostatic discharge (esd) to the duplex sc receptacle variation of iec 61000-4-2 typically withstand at least 15 kv without damage when the duplex sc connector receptacle is contacted by a human body model probe. electromagnetic interference (emi) fcc class b cenelec en55022 class b (cispr 22a) vcci class i margins are dependent on customer board and chassis designs. immunity variation of iec 61000-4-3 typically show no measurable effect from a 10 v/m field swept from 80 to 1000 mhz applied to the transceiver without a chassis enclosure. laser eye safety and equipment type testing us 21 cfr, subchapter j per paragraphs 1002.10 and 1002.12 en 60825-1: 1994 +a11 en 60825-2: 1994 + a1 en 60950: 1992+a1+a2+a3+a4+a11 ael class i, fda/cdrh accenssion #9521220-16 ael class 1, tuv rheinland of north certificate r02071007 component recognition underwriters laboratories and canadian standards association joint component recognition for information technology equipment including electrical business equipment. ul file e173874 (pending) rohs compliance less than 1000 ppm of cadmium, lead, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated biphenyl ethers.
4 provided the data pattern is reasonably balanced in duty factor. if the data duty factor has long, continuous 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. as for the receiver section, it is internally ac- coupled between the pre-amplifier and the postamplifier stages. the actual data and data- bar outputs of the postamplifier are dc-coupled to their respective output pins (pins 2, 3). signal detect is a single-ended, +5 v pecl 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 interconnection between the supporting physical layer integrated circuits and this hfct- 53d5 transceiver. figure 3 illustrates a recommended interface circuit for interconnecting to a +5 vdc pecl fiber-optic transceiver. some fiber-optic transceiver suppliers modules include internal capacitors, with or without 50 ohm termination, to couple their data and data-bar lines to the i/o pins of their module. when designing to use these type of transceivers along with avago technologies transceivers, it is important that the interface circuit can accommodate either internal or external capacitive coupling with 50 ohm termination components for proper operation of both transceiver designs. the internal dc-coupled design of the hfct-53d5 i/o connections was done to provide the designer with the most flexibility for interfacing to various types of circuits. eye safety circuit for an optical transmitter device to be eye- safe in the event of a single fault failure, the transmitter must either maintain normal, eye- safe operation or be disabled. the hfct-53d5 utilizes an integral fiber stub along with a current limiting circuit to guarantee eye-safety. it is intrinsically eye safe and does not require shut down circuitry. application support optical power budget and link penalties the worst-case optical power budget (opb) in db for a fiberoptic link is determined by the difference between 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 fiber-optic link. the opb is allocated for the fiber-optic cable length and the corresponding 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 identifies, and has modeled, the contributions of these opb penalties to establish the link length requirements for 62.5/125 mm and 50/125 mm multimode fiber usage. in addition, single-mode fiber with standard 1300 nm fabry-perot lasers have been modeled and specified. refer to the ieee 802.3z standard and its supplemental documents that develop the model, empirical results and final specifications. 10 km link support as well as complying with the lx 5 km standard, the hfct-53d5 specification provides additional margin allowing for a 10 km gigabit ethernet link on single mode fiber. this is accomplished by limiting the spectral width and center wavelength range of the transmitter while increasing the output optical power and improving sensitivity. all other lx cable plant recommendations should be followed. data line interconnections avago technologies hfct-53d5 fiber-optic transceiver is designed to directly couple to +5 v pecl signals. the transmitter inputs are internally dc-coupled to the laser driver circuit from the transmitter input pins (pins 7, 8). there is no internal, capacitively-coupled 50 ohm termination resistance within the transmitter input section. the transmitter driver circuit for the laser light source is a dc- coupled circuit. this circuit regulates the output optical power. the regulated light output will maintain a constant output optical power
5 signal detect the signal detect circuit provides a deasserted output signal that implies the link is open or the transmitter is off as defined by the gigabit ethernet specification 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 definite optical fault (e.g. unplugged connector for the receiver or transmitter, broken fiber, 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 electronic equipment. success in controlling generated 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. there are two options for the hfct-53d5 with regard to emi shielding which provide the designer with a means to achieve good emi performance. the emi performance of an enclosure using these transceivers is dependent on the chassis design. avago technologies encourages using standard rf suppression practices and avoiding poorly emi-sealed enclosures. the first configuration, option em, is for emi shielding applications where the position of the transceiver module will extend outside the equipment enclosure. the metallized plastic package and integral external metal shield of the transceiver helps locally to terminate em fields to the chassis to prevent their emissions outside the enclosure. this metal shield contacts the panel or enclosure on the inside of the aperture on all but the bottom side of the shield and provides a good rf connection to the panel. this option can accommodate various panel or enclosure thickness, i.e., .04 in. min. to 0.10 in. max. the reference plane for this panel thickness variation is from the front surface of the panel or enclosure. the recommended length for protruding the hfct- 53d5em transceiver beyond the front surface of the panel or enclosure is 0.25 in. with this option, there is flexibility of positioning the module to fit the specific need of the enclosure design. (see figure 5 for the mechanical drawing dimensions of this shield.) the second configuration, option fm, is for applications that are designed to have a flush mounting of the module with respect to the front of the panel or enclosure. the flush- mount design accommodates a large variety of panel thickness, i.e., 0.04 in. min. to 0.10 in. max. note the reference plane for the flush- mount design is the interior side of the panel or enclosure. the recommended distance from the centerline of the transceiver front solder posts to the inside wall of the panel is 0.55 in. this option contacts the inside panel or enclosure wall on all four sides of this metal shield. see figure 7 for the mechanical drawing dimensions of this shield. the two metallized designs are comparable in their shielding effectiveness. both design options connect only to the equipment chassis and not to the signal or logic ground of the circuit board within the equipment closure. the front panel aperture dimensions are recommended in figures 6 and 8. when layout of the printed circuit board is done to incorporate these metal- shielded transceivers, keep the area on the printed circuit board directly under the metal shield free of any components and circuit board traces. for additional emi performance advantage, use duplex sc fiber-optic connectors that have low metal content inside them. this lowers the ability of the metal fiber-optic connectors to couple emi out through the aperture of the panel or enclosure. evaluation kit to help you in your preliminary transceiver evaluation, avago technologies offers a 1250 mbd gigabit ethernet evaluation board (part # hfbr-0535). this board allows testing of the fiber-optic vcsel transceiver. it includes the hfct-53d5 transceiver, test board, and application instructions. in addition, a complementary evaluation board is available for the hdmp-1636a 1250 mbd gigabit ethernet serializer/ deserializer (serdes) ic.
