The AFCT-5805xxxZ is intended to enable commercial system designers to develop equipment that complies with the various regulations governing certifi cation of Information Technology Equipment. See the Regulatory Compliance Table 1 for details. Additional information is available from your Avago Technologies sales represen- tative. Electrostatic Discharge (ESD) There are two design cases in which immunity to ESD damage is important. The fi rst 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 fl oor mats in ESD controlled areas. The second case to consider is static discharges to the exterior of the equipment chassis containing the trans- ceiver parts. To the extent that the duplex SC 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 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. The AFCT-5805xxxZ has been characterized without a chassis enclosure to demonstrate the robustness of the part’s integral shielding. Performance of a system con- taining these transceivers within a well designed chassis is expected to be better than the results of these tests with no chassis enclosure. Immunity Equipment utilizing these AFCT-5805xxxZ transceivers will be subject to radio-frequency electromagnetic fi elds in some environments. These transceivers, with their inte- gral shields, have been characterized without the benefi t of a normal equipment chassis enclosure and the results are reported below. Performance of a system contain- ing these transceivers within a well designed chassis is expected to be better than the results of these tests without a chassis enclosure.
