3 / 15 page  3 Serial Identification (EEPROM) The HFBR-57E0 complies with the industry standard MSA that defines the serial identification protocol. This protocol uses the 2-wire serial CMOS E2PROM protocol of the ATMEL AT24C01A or equivalent. The contents of the HFBR-57E0 serial ID memory are defined in Table 3 as specified in the SFP MSA. Functional Data I/O The HFBR-57E0 fiberoptic transceiver is designed to ac- cept industry standard differential signals. In order to re- duce the number of passive components required on the customer’s board, Avago has included the functionality of the transmitter bias resistors and coupling capacitors within the fiberoptic module. The transceiver is compat- ible with an “ac-coupled” configuration and is internally terminated. Figure 5 depicts the functional diagram of the HFBR-57E0. Regulatory Compliance See Table 1 for transceiver Regulatory Compliance perfor- mance. The overall equipment design will determine the certification level. The transceiver performance is offered as a figure of merit to assist the designer. Table 1. Regulatory Compliance Feature Test Method Performance Electrostatic Discharge (ESD) to the Electrical Pins MIL-STD-883C Meets Class 2 (2000 to 3999 Volts).Withstand up to 2200 V applied between electrical pins. Electrostatic Discharge (ESD) to the Duplex LC Receptacle Variation of IEC 61000-4-2 Typically withstand at least 25 kV without damage when the LC connector receptacle is contacted by a Human Body Model probe. Electromagnetic Interference (EMI) FCC Class B CENELEC CEN55022 Class B (CISPR 21) VCCI Class 1 System margins are dependent on customer board and chassis design. Immunity Variation of IEC 61000-4-3 Typically shows a negligible effect from a 10 V/m field swept from 80 to 450 MHz applied to the transceiver without a chassis enclosure. Eye Safety AEL Class 1 EN60825-1 (+A11) Compliant per Avago testing under single fault conditions. TUV Certification: R 72042022 Component Recognition Underwriters Laboratories and Ca- nadian Standard Associations Joint Component Recognition for Informa- tion Technology Equipment Including Electrical Business Equipment UL File#: E173874 RoHS Compliance Reference to EU RoHS Directive 2002/95/EC Electrostatic Discharge (ESD) There are two conditions in which immunity to ESD damage is important. Table 1 documents our immunity to both of these conditions. The first condition is during handling of the transceiver prior to insertion into the transceiver port. To protect the transceiver, it is important to use normal ESD handling precautions. These precautions include using grounded wrist straps, workbenches, and floor mats in ESD controlled areas. The ESD sensitivity of the HFBR-57E0 is compatible with typical industry production environments. The second condition is static discharges to the exterior of the host equipment chassis after installation. To the extent that the duplex LC optical interface is exposed to the outside of the host equipment chassis, it may be subject to system- level ESD requirements. The ESD performance of the HFBR-57E0 exceeds typical industry standards. Immunity Equipment hosting the HFBR-57E0 modules will be sub- jected to radio-frequency electro magnetic fields in some environments. These transceivers have good immunity to such fields due to their shielded design. |
