Freescale Semiconductor
DDR and DDR2 SDRAM
Table 14 provides the recommended operating conditions for the DDR SDRAM component(s) when
GVDD(typ) = 2.5 V.

Notes:
1. GVDD is expected to be within 50 mV of the DRAM GVDD at all times.
2. MVREF is expected to equal 0.5 × GVDD, and to track GVDD DC variations as measured at the receiver. Peak-to-peak noise
on MVREF cannot 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 equal
MVREF. This rail should track variations in the DC level of MVREF.
4. Output leakage is measured with all outputs disabled, 0 V
≤ V
OUT ≤ GVDD.

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.
