12 Layout

12.1 Layout Guidelines

  • Data rates of 2.7Gbps require fast edge rate, which can cause EMI radiation if the pcb is not designed carefully.
  • Decoupling with small current loops is recommended.
  • It is recommended to place the de-coupling cap as close as possible to the device and on the same side of the pcb (see Figure 12).
  • Choose the capacitor such that the resonant frequency of the capacitor does not align closely with 2.7GHz.
  • Also provide several GND vias to the thermal pad to minimize the area of current loops.
