    DDR and DDR2 SDRAM
    This section describes the DC and AC electrical specifications for the DDR SDRAM interface of the
    MPC8548E. Note that GVDD(typ) = 2.5 V for DDR SDRAM, and GVDD(typ) = 1.8 V for DDR2
    SDRAM.
    6.1
    DDR SDRAM DC Electrical Characteristics
    Table 11 provides the recommended operating conditions for the DDR2 SDRAM controller of the
    MPC8548E when GVDD(typ) = 1.8 V.
    Table 12 provides the DDR2 I/O capacitance when GVDD(typ) = 1.8 V.

    Notes:
    1. GVDD is expected to be within 50 mV of the DRAM VDD 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
    ≤ VOUT ≤ 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.
