DD_33_AUX
B12 C09 This terminal is connected to VSS through a pulldown resistor,
since the XIO2213B does not support auxiliary power.
V
DDA_33
C03 A10 A01 C08 PWR Filter 3.3-V analog power for the link. This supply terminal is
separated from the other power terminals internal to the device
to provide noise isolation.
DVDD_CORE C09 F03 D08 D09 PWR Bypass Digital 1.95-V circuit power for the PHY. A combination of high-
M09 K09 capacitors frequency decoupling capacitors near each terminal is
suggested, such as paralleled 0.1 μF and 0.001 μF. An
additional 1-μF capacitor is required for voltage regulation.
These supply terminals are separated from the other power
terminals internal to the device to provide noise isolation.
PLLVDD_CORE M07 N06 PWR Bypass PLL 1.95-V circuit power for the PHY. A combination of high-
capacitors frequency decoupling capacitors near each terminal is
suggested, such as paralleled 0.1 μF and 0.001 μF. An
additional 1-μF capacitor is required for voltage regulation, and
the PLLVDD_CORE terminals must be separate from the
DVDD_CORE terminals. These supply terminals are separated
from the other power terminals internal to the device to provide
noise isolation.

PLLVDD_33 N07 N07 PWR Bypass PLL 3.3-V circuit power for the PHY. This supply terminal is
capacitors separated from the other power terminals internal to the device
to provide noise isolation. The PLLVDD_33 and V
DDA_33
pins
should be connected together with a low-dc-impedance
connection on the circuit board.
