pliant with the specifcations set forth in the ieee802.3 (1000base-sx) and the small form-factor pluggable (sfp) multi-source agreement (msa). this family of transceivers is qualifed in accordance with telcordia gr-468-core. its primary application is servicing gigabit ethernet links between optical networking equipment. the afbr-571 x z ofers maxi mum fexibility to designers, manufacturers, and operators of gigabit ethernet net - working equipment. a pluggable architec ture allows the module to be installed into msa standard sfp ports at any time C even with the host equipment operating and online. this facilitates the rapid confguration of equip - ment to precisely the users needs C reducing inventory costs and network downtime. compared with traditional transceivers, the size of the small form factor package enables higher port densities. module diagrams figure 1 illustrates the major functional components of the afbr-571 x z. the external confguration of the module is depicted in figure 7. figure 8 depicts the panel and host board footprints. 3 installation the afbr-571 x z can be installed in or removed from any msa-compliant pluggable small form factor port regard - less of whether the host equipment is operating or not. the module is simply inserted, electrical-interface frst, under fnger-pressure. controlled hot-plugging is ensured by 3 - stage pin sequencing at the electrical interface. this printed circuit board card-edge connector is depicted in figure 2. as the module is inserted, frst contact is made by the housing ground shield, discharging any potentially com - ponent-damaging static electricity. ground pins engage next and are followed by tx and rx power supplies. finally, signal lines are connected. pin functions and sequencing are listed in table 2. transmitter section the transmitter section includes the transmitter optical sub assembly (tosa) and laser driver circuitry. the tosa, containing an 850 nm vcsel (vertical cavity surface emit - ting laser) light source, is located at the optical interface and mates with the lc optical connector. the tosa is driven by a custom ic, which converts diferential logic signals into an analog laser diode drive current. this tx driver circuit regu - lates the optical power at a constant level provided the data pattern is dc balanced (8b10b code for example). transmit disable (tx_disable) the afbr-571 x z accepts a ttl and cmos compatible transmit disable control signal input (pin 3) which shuts down the transmitter optical output. a high signal imple - ments this function while a low signal allows normal transceiver operation. in the event of a fault (e.g. eye safety circuit activated), cycling this control signal resets the module as depicted in figure 6. an internal pull-up resistor disables the transceiver transmitter until the host pulls the input low. host systems should allow a 10ms interval between successive assertions of this control signal. tx_disable can also be asserted via the 2-wire serial interface (address a2h, byte 110, bit 6) and monitored (address a2h, byte 110, bit 7). the contents of a2h, byte 110, bit 6 are logic ord with hardware tx_disable (pin 3) to control transmitter opera - tion. transmit fault (tx_fault) a catastrophic laser fault will activate the transmitter signal, tx_fault, and disable the laser. this signal is an open collec - tor output (pull-up required on the host board). a low signal indicates normal laser operation and a high signal indicates a fault. the tx_fault will be latched high when a laser fault occurs and is cleared by toggling the tx_disable input or power cycling the transceiver. the transmitter fault condition can also be monitored via the 2-wire serial interface (address a2, byte 110, bit 2). eye safety circuit the afbr-571 x z provides class 1 eye safety by design and has been tested for compliance with the requirements listed in table 1. the eye safety circuit continu ously moni - tors optical output power levels and will disable the trans - mitter and assert a tx_fault signal upon detecting an unsafe condition. such unsafe conditions can be created by inputs from the host board (vcc fuxuation, unbalanced code) or faults within the module. receiver section the receiver section includes the receiver optical subas - sembly (rosa) and amplifcation/quantization circuitry. the rosa, containing a pin photodiode and custom trans-im - pedance preamplifer, is located at the optical interface and mates with the lc optical connector. the rosa is mated to a custom ic that provides post-amplifcation and quantiza - tion. also included is a loss of signal (los) detection circuit. receiver loss of signal (rx_los) the loss of signal (los) output indicates an unusable optical input power level. the loss of signal thresholds are set to indicate a defnite optical fault has occurred (e.g., disconnected or broken fber connection to receiver, failed transmitter, etc.). the post-amplifcation ic includes transition detection circuitry which monitors the ac level of incoming optical signals and provides a ttl/cmos compatible status signal to the host (pin 8). an adequate optical input results in a low rx_los output while a high rx_los output indicates an unusable optical input. the rx_los thresholds are fac - tory-set so that a high output indicates a defnite optical fault has occurred. for the afbr-5715z family, rx_los can also be monitored via the 2-wire serial interface (address a2h, byte 110, bit 1). 4 functional i/o the afbr-571 x z accepts industry standard diferential signals such as lvpecl and cml within the scope of the sfp msa. to simplify board requirements, transmitter bias resistors and ac coupling capacitors are incorporated, per sff-8074i, and hence are not required on the host board. the module is ac-coupled and internally terminated. figure 3 illustrates a recommended interface circuit to link the afbr-571 x z to the supporting physical layer integrated circuits. timing diagrams for the msa compliant control signals implemented in this module are depicted in figure 6. the afbr-571 x z interfaces with the host circuit board through twenty i/o pins (sfp electrical connector) identifed by function in table 2. the afbr-571 x z high speed transmit and receive interfaces require sfp msa compliant signal lines on the host board. the tx_disable, tx_fault, and rx_los lines require ttl lines on the host board (per sff-8074i) if used. if an application chooses not to take advantage of the functionality of these pins, care must be taken to ground tx_disable (for normal operation). figure 3. typical application confguration. laser drive r & eye safety circuitry 50 50 so1+ so1? amplification & quantization 50 50 si1+ si1? vrefr tbc ewrap rbc rx_rate rx_los gpio(x) gpio(x) gp14 tx_fault gp04 sync loop syn1 rc1(0:1) rfct tx[0:9] rx[0:9] tx_fault tx_disable veet rd+ rd? rx_los mod_def2 eeprom mod_def1 mod_def0 ref_rate note: * 4.7 k < res < 10 k v cc t,r 125 mhz avago afbr-571x z v cc t 1 h 1 h 10 f 0.1 f v cc t,r v cc r 10 f 0.1 f 0.1 f avago hdmp-168 7 r rcm0 c c refclk mac asic *res *res *res *res veer td+ td? c c r *res housing ground *res digital diagnostic interface and serial identifcation (eeprom) the entire afbr-571 x z family complies with the sff- 8074i sfp specifcation. the afbr-5715z family further complies with sff-8472, the sfp specifcation for digital diagnostic monitoring interface. both specifcations can be found at http://www.sfcommittee.org. the afbr-571 x z features an eeprom for serial id, which contains the product data stored for retrieval by host equipment. this data is accessed via the 2-wire serial eeprom protocol of the atmel at24c01a or similar, in compliance with the industry standard sfp multi-source agreement. the base eeprom memory, bytes 0-255 at memory address 0xa0, is organized in compliance with sff-8074i. contents of this serial id memory are shown in table 10. the i2c accessible memory page address 0xb0 is used internally by sfp for the test and diagnostic purposes and it is reserved. 5 as an enhancement to the conventional sfp interface defned in sff-8074i, the afbr-5715z family is compliant to sff-8472 (digital diagnostic interface for optical trans - ceivers). this new digital diagnostic information is stored in bytes 0-255 at memory address 0xa2.using the 2-wire serial interface defned in the msa, the afbr-5715z provides real time temperature, supply voltage, laser bias current, laser average output power and received input power. these parameters are internally calibrated, per the msa. the digital diagnostic interface also adds the ability to disable the transmitter (tx_disable), monitor for trans - mitter faults (tx_fault), and monitor for receiver loss of signal (rx_los). the new diagnostic information provides the oppor - tunity for predictive failure identifcation, compliance prediction, fault isolation and component monitoring. predictive failure identifcation the predictive failure feature allows a host to identify potential link problems before system performance is impacted. prior identifcation of link problems enables a host to service an application via fail over to a redun - dant link or replace a suspect device, maintaining system uptime in the process. for applications where ultra-high system uptime is required, a digital sfp provides a means to monitor two real-time laser metrics associated with ob - serving laser degradation and predicting failure: average laser bias current (tx_bias) and average laser optical power (tx_power). compliance prediction compliance prediction is the ability to determine if an optical transceiver is operating within its operating and environmental requirements. afbr-5715z devices provide real-time access to transceiver internal supply voltage and temperature, allowing a host to identify potential component compliance issues. received optical power is also available to assess compliance of a cable plant and remote transmitter. when operating out of requirements, the link cannot guarantee error free transmission. fault isolation the fault isolation feature allows a host to quickly pin - point the location of a link failure, minimizing downtime. for optical links, the ability to identify a fault at a local device, remote device or cable plant is crucial to speeding service of an installation. afbr-5715z real-time monitors of tx_bias, tx_power, vcc, temperature and rx_power can be used to assess local transceiver current operating conditions. in addition, status fags tx_disable and rx loss of signal (los) are mirrored in memory and available via the two-wire serial interface. component monitoring component evaluation is a more casual use of the afbr- 5715z real-time monitors of tx_bias, tx_power, vcc, tem - perature and rx_power. potential uses are as debugging aids for system installation and design, and transceiver parametric evaluation for factory or feld qualifcation. for example, temperature per module can be observed in high density applications to facilitate thermal evaluation of blades, pci cards and systems. required host board components the msa power supply noise rejection flter is required on the host pcb to meet data sheet performance. the msa flter incorporates an inductor which should be rated 400 madc and 1 ? series resistance or better. it should not be replaced with a ferrite. the required flter is illustrated in figure 4. the msa also specifes that 4.7 k to 10 k ? pull-up resis - tors for tx_fault, los, and mod_def0,1,2 are required on the host pcb. 1 h 1 h 0.1 f v cc r sfp module 10 f v cc t 0.1 f 10 f 3.3 v host board 0.1 f figure 4. msa required power supply flter. 6 fiber compatibility the afbr-571xz transciever is capable of transmission at 2 to 550 meters with 50/125 m fber, and at 2 to 275 meters with 62.5 125 m fber, for 1.25 gbd ethernet. it is capable of transmission up to 500m with 50/125 m fber and up to 300m with 62.5/125 m fber, for 1.0625 gbd fiber channel. application support to assist in the transceiver evaluation process, agilent ofers a 1.25 gbd gigabit ethernet evaluation board which facilitates testing of the afbr-571 x z. it can be obtained through the agilent field organization by ref - erencing agilent part number hfbr-0571. a reference design including the afbr-571 x z and the hdmp-1687 gigabit quad serdes is available. it may be obtained through the agilent field sales organization. regulatory compliance see table 1 for transceiver regulatory compliance. certi - fcation level is dependent on the overall confguration of the host equipment. the transceiver performance is ofered as a fgure of merit to assist the designer. electrostatic discharge (esd) the afbr-571 x z exceeds typical industry standards and is compatible with esd levels found in typical manufactur - ing and operating environments as described in table 1. there are two design cases in which immunity to esd damage is important. the frst case is during handling of the transceiver prior to insertion into the transceiver port. to protect the trans - ceiver, its important to use normal esd handling precau - tions. these precautions include using grounded wrist straps, work benches, and foor mats in esd controlled areas. the esd sensitivity of the afbr-571 x z is compat - ible with typical industry production environments. the second case to consider is static discharges to the exterior of the host equipment chassis after installation. to the extent that the optical interface is exposed to the outside of the host equipment chassis, it may be subject to system-level esd requirements. electromagnetic interference (emi) equipment using the afbr-571 x z family of transceivers is typically required to meet the require ments of the fcc in the united states, cenelec en55022 (cispr 22) in europe, and vcci in japan. the metal housing and shielded design of the afbr- 571xz minimize the emi challenge facing the host equip - ment designer. emi immunity equipment hosting afbr-571 x z modules will be sub - jected to radio-frequency electromagnetic felds in some environments. the transceiver has excellent immunity to such felds due to its shielded design. flammability the afbr-571 x z transceiver is made of metal and high strength, heat resistant, chemically resistant, and ul 94v-0 fame retardant plastic. customer manufacturing processes this module is pluggable and is not designed for aqueous wash, ir refow, or wave soldering processes. 7 table 1. regulatory compliance feature test method performance electrostatic discharge (esd)to the electrical pins jedec/eiajesd22-a114-a class 2 (> +2000 volts) electrostatic discharge (esd) to the duplex lc reseptacle variation of iec 6100-4-2 typically withstands at least 25 kv without damage when the duplex lc connector receptacle is contacted by a human body model probe electromagnetic interference(emi) fcc class b cenelec en55022 class b (cispr 22a) vcci class 1 applications with high sfp port counts are expected to be compliant; however, margins are dependent on customer board and chassis design. immunity variation of iec 61000-4-3 typically shows a negligible efect from a 10 v/m feld swept from 80 to 1000 mhz applied to the transceiver without a chassis enclosure. eye safety us fda cdrh ael class 1 en(iec)60825-1,2, en60950 class 1 cdrh certifcation #9720151-57 tuv fle rr72102090.01 component recognition underwriters laboratories and canadian standards association joint component recognition for information technology equipment including electrical business equipment ul file #e173874 rohs compliance less than 1000ppm of: cadmium, lead, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated biphenyl ethers. caution there are no user serviceable parts nor any maintenance required for the afbr-571 x z. all adjustments are made at the factory before shipment to our customers. tampering with, modifying, misusing or improp erly handling the afbr-571 x z will void the product warranty. it may also result in improper operation of the afbr-571 x z circuitry, and possible overstress of the laser source. device deg -
