Recommended Solder Fluxes and Cleaning/Degreasing
Chemicals
Recommended cleaning and degreasing chemicals for the
HFBR/HFCT-5208M are alcohols (methyl, isopropyl,
isobutyl), aliphatics (hexane, heptane) and other chemicals,
such as soap solution or naphtha. Do not use partially
halogenated hydrocarbons for cleaning/degreasing.
Examples of chemicals to avoid are 1,1.1 trichloroethane,
ketones (such as MEK), acetone, chloroform, ethyl acetate,
methylene dichloride, phenol, methylene chloride or
N methylpyrolldone.
Regulatory Compliance
These transceiver products are intended to enable
commercial system designers to develop equipment that
complies with the various regulations governing
certification of Information Technology Equipment. See the
Regulatory Compliance Table for details. Additional
information is available from your Avago Technolgies sales
representative.
Electrostatic Discharge (ESD)
There are two design cases in which immunity to ESD
damage is important.
The first 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 floor mats in ESD controlled areas, etc.
The second case to consider is static discharges to the
exterior of the equipment chassis containing the transceiver
parts. To the extent that the duplex SC connector receptacle
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 Technolgies will be required to
meet the requirements of FCC in the United States, CENELEC
EN55022 (CISPR 22) in Europe and VCCI in Japan.
The HFBR/HFCT-5208M EMI has been characterized with a
chassis enclosure to demonstrate the robustness of the
parts. Performance of a system containing these
transceivers will vary depending on the individual chassis
design.
Immunity
Equipment utilizing these HFBR/HFCT-5208M transceivers
will be subject to radio-frequency electromagnetic fields in
some environments. These transceivers, with their integral
shields, have been characterized without the benefit of a
normal equipment chassis enclosure and the results are
reported below. Performance of a system containing these
transceivers within a well- designed chassis is expected to
be better than the results of these tests without a chassis
enclosure.
