Notes:
1. D
n_GVDD is expected to be within 50 mV of the DRAM Dn_GVDD at all times.
2. D
n_MVREF is expected to be equal to 0.5 × Dn_GVDD, and to track Dn_GVDD DC variations as measured at the
receiver. Peak-to-peak noise on D
n_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 D
n_MVREF. This rail should track variations in the DC level of Dn_MVREF.
4. Output leakage is measured with all outputs disabled, 0 V
≤ VOUT ≤ Dn_GVDD.
