Electromagnetic Interference (EMI)
Most equipment designs utilizing this high speed trans-
ceiver from Avago Technologies will be required to meet
the require ments of FCC in the United States, CENELEC
EN55022 (CISPR 22) in Europe and VCCI in Japan.
Applications Support Materials
Contact your local Avago Technologies Component Field
Sales O ce for information on how to obtain PCB layouts
and evaluation boards for the 2 x 5 transceivers.
Immunity
Equipment utilizing these transceivers will be subject
to radio-frequency electromagnetic elds in some
environments. These transceivers have a high immunity
to such elds.
For additional information regarding EMI, susceptibility,
ESD and conducted noise testing
Board Layout- Art Work
The Applications Engineering group has developed Gerber
le artwork for a multilayer printed circuit board layout
incorporat-ing the recommendations above. Contact
your local Avago Technologies sales representative for
details.procedures and results on the 1 x 9 Transceiver
family, please refer to Applications Note 1075, Testing and
Measuring Electro magnetic Compatibility Perform ance of
the HFBR-510X/-520X Fiber Optic Transceivers.
