External Power Supply Access
All power supplies must be decoupled to Ground as close as possible to the signal accesses to the
board by 1 µF in parallel to 100 nF.
Each group of neighboring power supply pins attributed to the same value should be bypassed with at
least one pair of 100 pF capacitors in parallel to 10 nF capacitors. These capacitors should be placed as
close as possible to the power supply package pins.
The minimum required pairs of capacitors by power supply type is:
(V CCD and V PLUSD )
• 15 for V
