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_CORE, AVDD_PCI, AVDD_LBIU, and AVDD_SRDS, respectively). The AVDD
level should always be equivalent to VDD, and preferably these voltages will be 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 56, 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 footprint, without the inductance of vias.
Figure 56 through Figure 58 shows the PLL power supply filter circuits.
