Layout Considerations
Circuit board layout and design can significantly affect
the performance of the MAX3971A. Use good high-fre-
quency techniques, including fixed-impedance trans-
mission lines for the high-frequency data signal. Use a
multilayer board with solid ground plane. Minimize the
inductance between the MAX3971A and the ground
plane.
The MAX3971A uses three power-supply pins (VCC1,
VCC2, and VCC3). The input circuitry of the MAX3971A is
supplied by VCC1. The output drivers have a separate
supply (VCC3), which usually has large pulsing currents.
All other circuitry is powered by VCC2. It is possible to
simply connect the three pins together. However, using a
supply filter ensures better isolation of the input circuitry.
For optimal isolation, Figure 5 shows a possible supply-
filtering circuit. Element L, a ferrite bead, provides isola-
tion between a noisy VCC3 and a sensitive VCC1.
