Power Supplies and Layout
The HI5714 Evaluation Board is a four layer board with a
layout optimized for the best performance for the ADC.
Figures 11 through 16 include a schematic of the board, a
board layout, and the various board layers. The user should
feel free to copy the layout in their application.
In order optimize the performance of the HI5714 at power
up, it is necessary that AV
separate supplies. The supplies to the board should be
driven by clean linear regulated supplies. AGND and DGND
are tied together under

the HI5714. Do not tie the supply grounds together back at
the supplies as this will create a ground loop and generate
additional noise.
Decoupling capacitors should be placed as close to the
HI5714 as possible. A 0.1µF and a 0.001µF leaded capacitor
will provide good decoupling but chip capacitors will provide
better decoupling at higher clock frequencies. Do not forget
a large value cap (1µF to 10µF) for low frequency
decoupling somewhere on your PC board.
