Designing a PC Board
Good PC board layout is important to achieve optimal
performance from the MAX1565. Poor design can
cause excessive conducted and/or radiated noise.
Conductors carrying discontinuous currents, and any
high-current path should be made as short and wide as

possible. A separate low-noise ground plane containing
the reference and signal grounds should connect to the
power-ground plane at only one point to minimize the
effects of power-ground currents. Typically, the ground
planes are best joined right at the IC.
