DDR2 and DDR3 SDRAM
This section describes the DC and AC electrical specifications for the DDR SDRAM interface of the chip. Note that DDR2
SDRAM is GVDD(type) = 1.8 V and DDR3 SDRAM is GVDD(type) = 1.5 V.

Notes:
1. GVDD is expected to be within 50 mV of the DRAM GVDD at all times.
2. MVREF is expected to be equal to 0.5 × GVDD, and to track GVDD DC variations as measured at the receiver.
Peak-to-peak noise on MVREF may not exceed ±2% of the DC value.
3. VTT is not applied directly to the chip. It is the supply to which far end signal termination is made and is expected to be
equal to MVREF. This rail should track variations in the DC level of MVREF.
4. Output leakage is measured with all outputs disabled, 0 V
≤ VOUT ≤ GVDD.
