DDR (2.5V) SDRAM DC Electrical Characteristics
Table 7 provides the recommended operating conditions for the DDR SDRAM component(s) of the MSC8144 when
VDDDDR(typ) = 2.5 V.
Table 8 lists the current draw characteristics for MVREF.

Notes:
1.
VDDDDR is expected to be within 50 mV of the DRAM VDD at all times.
2.
MVREF is expected to be equal to 0.5 × VDDDDR, and to track VDDDDR 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 VDDDDR.
