ATVDD/ATVSS 0.1
μF (x16) + 1μF (x8) + 10μF (x4)
It is recommended to use one 0.1
μF cap for each
ATVDD/ATVSS pair (16 total), one 1
μF for every
two ATVDD/ATVSS pairs (8 total), and four 10
μF
capacitors for the analog transmit supply pins.
These capacitors should be located as close to the
intended power pins as possible.
