G2993
Global Mixed-mode Technology Inc.
In Figure 5 & 6, they are the application configurations
of DDR-II SDRAM bus terminations. Figure 5 is the
typical application scheme of DDR-II SDRAM. With
the separate VDDQ pin and an internal resistor divider,
it is possible to use the G2993 in applications utilizing
DDR-II memory. Figure 6 is used to increase the driv-
ing capability. The risk is the same as figure 4.
