Power Supply Design
21.2.1
PLL Power Supply Filtering
Each of the PLLs listed above is provided with power through independent power supply pins
(AVDD_PLAT, AVDD_CORE0, AVDD_CORE1, AVDD_DDR, AVDD_LBIU, AVDD_SRDS1 and
AVDD_SRDS2 respectively). The AVDD level should always be equivalent to VDD, and preferably these
voltages are derived directly from VDD through a low frequency filter scheme such as the following.
There are a number of ways to reliably provide power to the PLLs, but the recommended solution is to
provide independent filter circuits per PLL power supply as illustrated in Figure 62, one to each of the
AVDD pins. By providing independent filters to each PLL the opportunity to cause noise injection from
one PLL to the other is reduced.
This circuit is intended to filter noise in the PLLs resonant frequency range from a 500 kHz to 10 MHz
range. It should be built with surface mount capacitors with minimum Effective Series Inductance (ESL).
Consistent with the recommendations of Dr. Howard Johnson in High Speed Digital Design: A Handbook
of Black Magic (Prentice Hall, 1993), multiple small capacitors of equal value are recommended over a
single large value capacitor.
Each circuit should be placed as close as possible to the specific AVDD pin being supplied to minimize
noise coupled from nearby circuits. It should be possible to route directly from the capacitors to the AVDD
pin, which is on the periphery of the 1023 FC-PBGA footprint, without the inductance of vias.
Figure 62 shows the PLL power supply filter circuits.
Figure 62. PLL Power Supply Filter Circuit
NOTE
It is recommended to have the minimum number of vias in the AVDD trace
for board layout. For example, zero vias might be possible if the AVDD filter
is placed on the component side. One via might be possible if it is placed on
the opposite of the component side. Additionally, all traces for AVDD and
the filter components should be low impedance, 10 to 15 mils wide and
short. This includes traces going to GND and the supply rails they are
filtering.
The AVDD_SRDSn signal provides power for the analog portions of the SerDesn PLL. To ensure stability
of the internal clock, the power supplied to the PLL is filtered using a circuit similar to the one shown in
following figure. For maximum effectiveness, the filter circuit is placed as closely as possible to the
AVDD_SRDSn ball to ensure it filters out as much noise as possible. The ground connection should be near
the AVDD_SRDSn ball. The 0.003-F capacitor is closest to the ball, followed by the two 2.2 F
capacitors, and finally the 1
Ω resistor to the board supply plane. The capacitors are connected from
