DESCRIPTION
SRIO interface supply:
1.25-V core supply voltage (-1000 and -1200 devices)
1.2-V core supply voltage (-850 devices).
The source for this supply voltage must be the same as that of CV_DD.
NOTE: If RapidIO is not used, these pins can be connected directly to V_SS.
Main SRIO supply:
1.25-V I/O supply voltage (-1000 and -1200 devices)
1.2-V I/O supply voltage (-850 devices).
Do not use core supply.
NOTE: If RapidIO is not used, these pins can be connected directly to V_SS.
SRIO termination supply:
1.25-V I/O supply voltage (-1000 and -1200 devices)
1.2-V I/O supply voltage (-850 devices).
Do not use core supply.
NOTE: If RapidIO is not used, these pins can be connected directly to V_SS.
1.8-V or 1.5-V I/O supply voltage for the RGMII function of the EMAC.
NOTE: If the RGMII mode of the EMAC is not used, the DV_DD15, V_REFHSTL,
RSV13, and RSV14 pins can be connected to directly ground (V_SS) to save
power. However, connecting these pins directly to ground will prevent
boundary-scan from functioning on the RGMII pins of the EMAC. To preserve
boundary-scan functionality on the RGMII pins, see Section 7.3.4.
1.8-V I/O supply voltage (DDR2 Memory Controller)
