1GHz. This can be achieved by using one 22µF (1210 case
size, CERAMIC), nine 0.1µF (0402 case size, ceramic), and
nine 0.01µF (0402 case size, ceramic) capacitors in parallel.
The 0.01µF and 0.1µF 0402 case size capacitors must be
placed right next to the VDDA balls as close as possible.
Note that the 22µF capacitor must be of 1210 case size, and
it must be ceramic for lowest ESR possible. The 0.01µF
must be of case size 0402, this offers the lowest ESL to
achieve low impedance towards the GHz range. Also, note
that the ground of these capacitors must be connected to
GNDA.
VDD (1.8V) is the power rail for the core logic circuit. For the
VDD, at least six 0.1µF (0402 case size), six 0.01µF (0402
case size) and a 10µF (tantalum) capacitor are
recommended. Place the 0.01µF and 0.1µF capacitors as
close to the VDD balls as possible.
V_DDQ (1.8V or 2.5V) is the power rail for all the low speed
I/O drivers; at least ten 0.01µF (0402 case size), ten 0.1µF
(0402 case size) capacitors are recommended. Place the
0.01µF and 0.1µF capacitors as close to the V_DDQ balls as
possible.
