Preliminary data sheet
10.2.1 The 3.3 V Analog Supply
10.2.2 The SoC Core, VDDA, Analog Supply
10.2 Analog Supplies
Other devices like the DDR memory devices also require local decoupling capacitors.
At least eight 0.1 F capacitors (one for each VDD or VDDQ) combined with one 22
additional eight 0.01
per device is also recommended.
Additional global decoupling can also be distributed across the board.
The entire analog ground/supply is kept free-floating on the PCB.
Quiet VCCA for the PLL subsystem should be supplied from VCCP through a 18
series resistor. It should be bypassed for AC to VSSA, using a dual capacitor bypass
(hi and low frequency AC bypass).
Quiet VSSA for the PLL subsystem: the bypass should only be connected to the
PNX1700 VSSA[] pins and not to the global VSS (i.e. ground) network. No external
coil or other connection to board ground is needed, such connection would create a
ground loop.
