Electromagnetic Interference (EMI)

One of a circuit board designer’s foremost concerns is

the control of electromagnetic emissions from electronic

equipment. Success in controlling generated Electromag-

netic Interference (EMI) enables the designer to pass a

governmental agency’s EMI regulatory standard; and more

importantly, it reduces the possibility of interference to

neighboring equipment. There are three options available

for the HFBR-5208xxxZ with regard to EMI shielding for

providing the designer with a means to achieve good

EMI performance. The EMI performance of an enclosure

using these transceivers is dependent on the chassis

design. Avago encourages using standard RF suppression

practices and avoiding poorly EMI-sealed enclosures. In

addition, Avago advises that for the best EMI performance,

the metalized case must be connected to chassis ground

using one of the shield options.
