A. DM648 is shown in this figure as an example of the device and represents the entire set of devices that include:
DM647/DM648.
B. V_io 1.8 is the power supply for the DDR2 memory interface.
C. One of these capacitors can be eliminated if the divider and its capacitors are placed near a device VREF pin.
