description the afbr-56xxz/afct-56xxz family of interface convert - ers meet the gigabit interface converter specifcation rev. 5.4, an industry standard. the family provides a uniform form factor for a wide variety of standard con - nections to transmission media. the converters can be inserted or removed from a host chassis without remov - ing power from the host system. the converters are suitable for interconnections in the gigabit ethernet hubs and switches environment. the design of these converters is also practical for other high performance, point-to-point communication requiring gigabit interconnections. since the converters are hot- pluggable, they allow system confguration changes simply by plugging in a diferent type of converter. the mechanical and electrical interfaces of these convert - ers to the host system are identical for all implementa - tions of the converter regardless of external media type. a 20-pin connector is used to connect the converter to the host system. surge currents are eliminated by using pin sequencing at this connector and a slow start circuit. two ground tabs at this connector also make contact before any other pins, discharging possible component- damaging static electricity. in addition, the connector it - self performs a two-stage contact sequence. operational signals and power supply ground make contact in stage 1 while power makes contact in stage 2. applications ? switch to switch interface ? high speed i/o for fle servers ? bus extension applications features ? rohs compliance ? compliant with gigabit interface converter specifcation rev. 5.4 (1) ?

2 the AFBR-5601Z has been developed with 850 nm short wavelength vcsel technology while the afct-5611z is based on 1300 nm long wavelength fabry perot laser technology. the AFBR-5601Z complies with annex g of the gbic specifcation revision 5.4. in the 1000 base-sx environ - ment the AFBR-5601Z achieves 220 m transmission distance with 62.5 m and 500 m with 50 m multimode fber respectively. the afct-5611z complies with annex f of the gbic specifcation revision 5.4 and reaches 10 km with 9/125 m single mode fber. both the AFBR-5601Z and the afct-5611z are class 1 eye safe laser devices. serial identifcation the afbr-56xxz and afct-5611z family complies with annex d (module defnition 4) of the gbic specifca - tion revision 5.4, which defnes the serial identifcation protocol. defnition 4 specifes a serial defnition protocol. for this defnition, upon power up, mod_def(1:2) (pins 5 and 6 on the 20-pin connector) appear as nc. pin 4 is ttl ground. when the host system detects this condition, it activates the public domain serial protocol. the protocol uses the 2-wire serial cmos e 2 prom protocol of the at - mel at24c01a or similar. the data transfer protocol and the details of the manda - tory and vendor specifc data structures are defned in annex d of the gbic specifcation revision 5.4. regulatory compliance see the regulatory compliance table for the targeted typical and measured performance for these transceiv - ers. the overall equipment design will determine the level it is able to be certifed to. these transceiver performance targets are ofered as a fgure of merit to assist the de - signer in considering their use in equipment designs. note: AFBR-5601Z is non-compliant for tx fault timing. 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 inserting it into the host system. it is important to use normal esd handling precautions for esd sensitive devices. these precautions include using grounded wrist straps, work benches, and foor mats in esd controlled areas. the second case to consider is static discharges during insertion of the gbic into the host system. there are two guide tabs integrated into the 20-pin connector on the gbic. these guide tabs are connected to circuit ground. when the gbic is inserted into the host system, these tabs will engage before any of the connector pins. the mating connector in the host system must have its tabs connected to circuit ground. this discharges any stray static charges and establishes a reference for the power supplies that are sequenced later. electromagnetic interference (emi) most equipment designs utilizing these high-speed trans - ceivers 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. immunity equipment utilizing these transceivers will be subject to radio-frequency electromagnetic felds in some environ - ments. these transceivers have good immunity to such felds due to their shielded design. eye safety laser-based gbic transceivers provide class 1 (iec 60825- 1) and class i (us 21 cfr[j]) laser eye safety by design. avago technologies has tested the current transceiver design for compliance with the requirements listed below under normal operating conditions and for compliance under single fault conditions. outline drawing an outline drawing is shown in figure 1. more detailed drawings are shown in gigabit interface converter speci - fcation rev. 5.4.

6 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 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 fber-optic link. the opb is allocated for the fber-optic cable length and the corr e sponding link penalties. for proper link perfor m ance, all penalties that afect the link performance must be ac c ounted for within the link optical power bud - get. the gigabit/sec ethernet (gbe) 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 mult i mode fber usage. in addi - tion, single-mode fber with standard 1300 nm fabry perot lasers have been modeled and specifed. refer to ieee 802.3z standard and its supplemental documents that develop the model, empirical results and fnal specifcations. 10 km link support as well as complying with the lx 5 km standard, the afct- 56xxz specifcation provides additional margin allowing for a 10 km gigabit ethernet link on single mode fber. this is accomplished by limiting the spectral width and center wavelength range of the transmitter while increas - ing the output optical power and improving sensitivity. all other lx cable plant recommendations should be followed. caution: there are no user serviceable parts nor any maintenance required for the afbr-56xxz and afct-56xxz product family. all adjustments are made at the factory before shipment to our customers. tampering with or modify - ing the performance of any avago technologies gbic unit will result in voided product warranty. it may also result in improper operation of the circuitry, and possible overstress of the semiconductor components. device degradation or product failure may result. connection of either the AFBR-5601Z or the afct-5611z to a non-approved optical source, operating above the recommended absolute maximum conditions, or op - erating in a manner inconsistent with unit 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 the laser product under the provisions of us 21 cfr (subchapter j). regulatory compliance feature test method targeted performance electrostatic discharge (esd) to the electrical pins mil-std-883c method 3015.7 class 1 (>2000 v) electrostatic discharge (esd) to the duplex sc receptacle variation of iec 61000-4-2 typically withstand at least 15 kv without damage when port is contacted by a human body model probe. electromagnetic interference (emi) fcc class b cenelec en55022 class b (cispr 22a) vcci class 1 margins are dependent on customer board and chassis design. immunity variation of iec 61000-4-3 typically show no measurable efect from a10 v/m feld swept from 27 to 1000 mhz applied to the transceiver without a chassis enclosure laser eye safety us 21 cfr, subchapter j perparagraphs 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 AFBR-5601Z accession no. 9720151-51 afct-5611z accession no. 9521220-120ael class 1, tuv rheinland of north america AFBR-5601Z certifcate no. r72040311.004 afct-5611z certifcate no. 933/21201880/04 protection class iii component recognition underwriters laboratories and canadian standards association joint component recognition for information technology equipment including electrical business equipment. ul file e173874 rohs compliance compliant to eu directive 2002/95/ec.

8 short wavelength gbic: AFBR-5601Z transmitter section the transmitter section consists of an 850 nm vcsel in an optical subassembly (osa), which mates to the fber cable. the vcsel osa is driven by a custom, silicon bi - polar ic which converts diferential logic signals into an analog laser diode drive current. receiver section the receiver includes a gaas pin photodiode mounted together with a custom, silicon bipolar transimpedance preamplifer ic, in an osa. the osa interfaces to a cus - tom silicon bipolar circuit that provides post-amplifca - tion and quantization. the post-amplifer includes a signal detect circuit that provides ttl compatible logic- low output in response to the detection of a usable input optical signal. absolute maximum ratings stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. limits apply to each parameter in isolation, all other parameters having values within the recommended operating conditions. it should not be assumed that limiting values of more than one parameter can be applied to the product at the same time. exposure to the absolute maximum ratings for extended periods can adversely afect device reliability. parameter symbol min. typ. max. unit notes storage temperature t s -40 +85 c supply voltage v dd t v dd r -0.5 6.0 v data input voltage tx_dat -0.5 v dd t v 1 transmitterdiferential input voltage tx_dat 2000 mv p-p relative humidity rh 5 95 % parameter symbol min. typ. max. unit notes ambient operating temperature t a 0 +60 c case temperature t case +75 c 2 supply voltage v dd t v dd r 4.75 5.0 5.25 v supply current i tx + i rx 200 300 ma 3 parameter symbol min. typ. max. unit notes surge current i surge +30 ma 4 power dissipation p diss 1.00 1.58 w 5 notes: 1. up to applied v dd t. 2. see figure 1 for measurement point. 3. maximum current is specifed at v cc = maximum @ maximum operating temperature and end of life. 4. hot plug above actual steady state current. 5. total t x + r x . eye safety design the laser driver is designed to be class 1 eye safe (cdrh21 cfr(j), iec 60825-1) under a single fault condi - tion. to be eye safe, only one of two results can occur in the event of a single fault. the transmitter must either maintain normal eye safe operation or the transmitter should be disabled. there are three key elements to the safety circuitry: a monitor diode, a window detector 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 dc regulation circuit cannot maintain the preset bias conditions within 20%, the transmitter will automatically be disabled. once this has occurred, an electrical power reset will allow an at - tempted turn-on of the transmitter. tx_fault can also be cleared by cycling tx_disable high for a time interval > 10 s. transceiver electrical characteristics (t a = 0c to +60c, v cc = 4.75 v to 5.25 v) recommended operating conditions
