PRODUCTION DATA
See Figure 10-1 for an example with continuous ground planes (except where clear areas are needed to provide appropriate impedance management for specific signals). Power is provided on one plane, with the 1.9-V ADC supply being split into multiple zones or peninsulas for the specific power buses of the ADC. Decoupling capacitors are connected between these power bus peninsulas and the adjacent ground planes using vias. The capacitors are located as close as possible to the individual power/ground pin pairs of the ADC. In most cases, this means the capacitors are located on the opposite side of the PCB to the ADC.
