10 Layout

10.1 Layout Guidelines

  1. Use Figure 35 configuration for powering the device.
    2. static_voltage_example.gifFigure 35. Recommended Setup for Powering Device
  2. Place decoupling cap(s) next to every supply pin to the ground plane close by.
  3. Use a multi-layer boards as shown in Figure 35 to ease routing, and to provide a low inductance ground plane.
  4. Beware of via inductance and when necessary increase the number and / or diameter of vias to reduce inductance
  5. Use ground plane “keep out” areas under sensitive nodes to minimize parasitic capacitance
