General PCB Layout Recommendations
For optimum device performance and lowest output
phase noise, the following guidelines should be
observed.
1. Each 0.01μF decoupling capacitor should be
mounted on the component side of the board as close
to the VDD pin as possible.
2. No vias should be used between decoupling
capacitor and VDD pin.
3. The PCB trace to VDD pin should be kept as short
as possible, as should the PCB trace to the ground via.
Distance of the ferrite bead and bulk decoupling from
the device is less critical.
4. An optimum layout is one with all components on the
same side of the board, minimizing vias through other
signal layers (any ferrite beads and bulk decoupling
capacitors can be mounted on the back). Other signal
traces should be routed away from the
ICS557-05A.This includes signal traces just
underneath the device, or on layers adjacent to the
ground plane layer used by the device.
