9 / 15 page  100 Electrostatic Discharge There are two design cases in which immunity to ESD damage is important. The first 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 precau- tions include using grounded wrist straps, work benches, and floor mats in ESD-controlled areas. The second case to consider is static discharges to the exterior of the equipment chassis con- taining the transceiver parts. To the extent that the MIC connector is exposed to the outside of the equipment chassis, it may be subject to whatever ESD system level test criteria that the equipment is intended to meet. Electromagnetic Interference (EMI) Most equipment designs utilizing these high speed transceivers from Hewlett-Packard will be required to meet the require- ments of FCC in the United States, CENELEC EN55022 (CISPR 22) in Europe and VCCI in Japan. Hence, the HFBR-511X Series of fiber optic transceivers meet the regulatory requirements listed in Table 1. Immunity Equipment utilizing these transceivers will be subject to radio-frequency electromagnetic fields in some environments. These transceivers have a high immunity to such fields. The internal construction of the HFBR-511X Series is similar to that of the HFBR-510X/-520X series. Therefore, for additional information regarding EMI sus- ceptibility, ESD, and conducted noise testing procedures and results, please refer to Applica- tion Note 1075, Testing and Measuring Electromagnetic Compatibility Performance of the HFBR-510X/-520X Fiber Optic Transceivers. Flammability Rating The housing material of the HFBR-5111/-5112/-5113 trans- ceiver has been approved for UL flammability rating of 94V-0 under General Electric’s UL file number E121562 and similarly under CSA file number LS88480. Transceiver Reliability and Performance Qualification Data As with all HP components, the HFBR-511X series transceivers undergo extensive Hewlett- Packard reliability and perform- ance qualification testing. Details are available from your Hewlett- Packard sales representative. These transceivers are manu- factured at the Hewlett-Packard Singapore location which is an ISO 9001 certified facility. Ordering Information The Hewlett-Packard FDDI transceivers are available packaged with or without key inserts per Table 2. The key inserts are colored-coded plastic parts with an identifying key letter molded into the top surface of each key. The HFBR-5111/-5112/-5113 products are available through the Hewlett-Packard Component Field Sales Offices and Authorized Distributors worldwide. Table 1. Regulatory Compliance Table Feature Test Method Performance Electrostatic Discharge MIL-STD-883C Meets Class 2 (2000 to 3999 Volts) (ESD) to the Electrical Pins Method 3015.4 Withstands up to 2200 V applied between electrical pins. Electrostatic Discharge Variation of IEC 801-2 Typically withstand at least 25 kV without (ESD) to the MIC Receptacle damage when the MIC Receptacle is contacted by a Human Body Model probe. Electromagnetic Interference FCC Class B Typically provide a 13 dB margin to the noted (EMC) CENELEC CEN55022 standard limits when tested at a certified Class B (CISPR 22B) test range with the transceiver mounted to a VCCI Class 2 circuit card without a chassis enclosure. Immunity Variation of IEC 801-3 Typically show no measurable effect from a 10 V/m field swept from 10 to 450 MHz applied to the transceiver when mounted to a circuit card without a chassis enclosure. |
