Hi,
We are designing intel pine m platform notebooks with ddr3 support. When I have
performing voltage margin test, I have noticed that DDR3 Vref value can be
between 0 and 1.5V. In our previous designs with DDR2, voltage levels were
between 0.3-0.5V at low side and 1.1-1.4V at high sideand margins were 0.5-1.2.
I couldnot comment these results for ddr3? Can you help me? What is the wrong?
Thanks.
Best Regards
Mustafa
