POWER AND GROUNDING CONSIDERATIONS AND
POWER SUPPLY REJECTION
Many applications seek high speed and performance under less
than ideal operating conditions. In these application circuits,
the implementation and construction of the PCB is as important
as the circuit design. Proper RF techniques must be used for
device selection, placement, and routing, as well as for power
supply bypassing and grounding to ensure optimum performance.
Each power supply pin should have independent decoupling and
connections to the power supply plane. It is recommended that the
device exposed paddle be directly connected to the ground plane
by a grid of at least nine vias. Care should be taken to ensure that
the output traces cannot couple onto the reference or crystal input
circuitry. Traces should not be routed under the crystal. Output
signal traces should be kept on the top PCB layer; these traces have
very high edge rates, and the use of PCB vias will result in signal
integrity problems.
