4. Regulatory Information
LITELINK III can be used to build products that comply
with the requirements of TIA/EIA/IS-968 (formerly
FCC part 68), FCC part 15B, TBR-21, EN60950,
UL1950, EN55022B, IEC950/IEC60950, CISPR22B,
EN55024, and many other standards. LITELINK
provides supplementary isolation. Metallic surge
requirements are met through the inclusion of a crow
bar protection device in the application circuit.
Longitudinal surge protection is provided by
LITELINK’s optical-across-the-barrier technology and
the use of high-voltage components in the application
circuit as needed.
5. LITELINK Design Resources
The IXYS Integrated Circuits Division web site has a
wealth of information useful for designing with
LITELINK, including application notes and reference
designs that already meet all applicable regulatory
requirements. LITELINK data sheets also contains
additional application and design information. See the
following links:

The information provided in this document is intended
to inform the equipment designer but it is not sufficient
to assure proper system design or regulatory
compliance. Since it is the equipment manufacturer's
responsibility to have their equipment properly
designed to conform to all relevant regulations,
designers using LITELINK are advised to carefully
verify that their end-product design complies with all
applicable safety, EMC, and other relevant standards
and regulations. Semiconductor components are not
rated to withstand electrical overstress or electrostatic
discharges resulting from inadequate protection
measures at the board or system level.
