Note:
1 GV
DD is expected to be within 50 mV of the DRAM GVDD at all times.
2 MV
REF 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 V
TT 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.
5 See AN3665, MPC837xE Design Checklist, for proper DDR termination.

Note:
1 The voltage regulator for MV
REF must be able to supply up to the stated maximum current.
2 This current is divided equally between MVREF1 and MVREF2, where half the current flows through each pin.
