3.6.3 Mode Pin Usage

Assert the MODE pin low to introduce a 7 dB pad into

the transmit path and add 7 dB of gain to the receive

path. These changes compensate for the gain

changes made to the transmit and receive paths in

reactive termination implementations.

Insertion loss with MODE de-asserted and the

resistive termination application circuit is 0 dB.

Insertion loss with the reactive termination application

circuit and MODE asserted is also 0 dB.

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

Sidactor in the application circuit. Longitudinal surge

protection is provided by LITELINK’s optical barrier

technology and the use of high-voltage components in

the application circuit as needed.

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 electro-static

discharges resulting from inadequate protection

measures at the board or system level.

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. See the following links:
