DDR2 SDRAM
6DDR2 SDRAM
This section describes the DC and AC electrical specifications for the DDR2 SDRAM interface. Note that
DDR2 SDRAM is GVDD(typ) = 1.8 V.

DDR2 SDRAM DC Electrical Characteristics
This table provides the recommended operating conditions for the DDR2 SDRAM component(s) when
GVDD(typ) = 1.8 V.
This table provides the DDR2 capacitance when GVDD(typ) = 1.8 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 device. 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

Note:
1. This parameter is sampled. GVDD = 1.8 V ± 0.090 V, f = 1 MHz, TA = 25°C, VOUT = GVDD/2, VOUT (peak-to-peak) = 0.2 V.
