Applications Information

Layout Considerations

To minimize loss and crosstalk, keep connections

between the MAX3863 output and the laser diode as

short as possible. Use good high-frequency layout

techniques and multilayer boards with uninterrupted

ground plane to minimize EMI and crosstalk. Circuit

boards should be made using low-loss dielectrics. Use

controlled-impedance lines for the clock and data

inputs, as well as the module output.

failure of a Maxim product could create a situation

where personal injury or death may occur.

Laser Safety and IEC 825

Using the MAX3863 laser driver alone does not ensure

that a transmitter design is compliant with IEC825. The

entire transmitter circuit and component selections

must be considered. Determine the level of fault toler-

ance required by each application and recognize that

Maxim products are not designed or authorized for use

as components in systems intended for surgical im-

plant into the body, for applications intended to support

or sustain life, or for any other application where the
