RK3288 Hardware Design Guide
Lighted trace in the figure connected to the FB end of DC/DC, is the feedback trace which
should be routed in parallel with power layer without any interference by other high-speed
signal traces in the same layer or other layers.
Fig 5-7
The large capacitors should be located in far-end
(
load end
)
of VDD_CPU, VDD_GPU,
VDD_LOG, VCC_DDR power; Place more than 40uF capacitors on the reverse side(or close to
CPU on same layer) of VDD_CPU, VDD_GPU SOC, more than 10uF capacitors for VDD_LOG,
VCC_DDR if possible, to improve the quality of power supply, enhance the performance of
products, and guarantee the stability of products shown as Fig 5-8.
