Notes:
1.
The value of VDDM at the MSC7118 device must remain within 50 mV of VDDM at the DRAM device at all times.
2.
VREF must be equal to 50% of VDDM and track VDDM variations as measured at the receiver. Peak-to-peak noise must not
exceed ±2% of the DC value.
3.
VTT is not applied directly to the MSC7118 device. It is the level measured at the far end signal termination. It should be equal
to VREF. This rail should track variations in the DC level of VREF.
4.
Output leakage for the memory interface is measured with all outputs disabled, 0 V
≤ VOUT ≤ VDDM.
5.
The core power values were measured.using a standard EFR pattern at typical conditions (25°C, 300 MHz, 1.2 V core).

Note:
These values were measured under the following conditions:
VDDM = 2.5 V ± 0.125 V
f = 1 MHz
TA = 25°C
VOUT = VDDM/2
VOUT (peak to peak) = 0.2 V
