Application Information (Cont.)
Application_2: Lower Power Loss Configuration for
SSTL-2
If power loss is a major concern, separating the PVCC
form AVCC and VDDQ will be a good choice (Figure 2).
The PVCC can operate at lower voltage (1.8V to 2.5V) if
2.5V voltage is applied on AVCC and the VDDQ, the source
current is lower due to the lower operating voltage ap-
plied on the PVCC.
Figure 2: Lower power loss for SSTL-2(DDR-I).
Application_3: High Source Current Configuration
If there is a need for VTT to source more current, espe-
cially for DDR-II applications, the system designer can tie
the AVCC and PVCC to 3.3V while has the VDDQ tie to 1.
8V. This configuration can ensure more than 2A source
and sink capability from the VTT rail.
Figure 4: High current set up for SSTL-18(DDR-II).
Notes:
(a) The preferred configuration for DDR-I applications
is to tie AVCC and PVCC to VDDQ, which is typically 2.5V.
(b) If AVCC and PVCC rails are tied together, then the
VDDQ cannot lead the AVCC and PVCC.
