Notes :
1. Includes ± 25mV margin for DC offset on VREF, and a combined total of ± 50mV margin for all AC noise and DC
offset on VREF, bandwidth limited to 20MHz. The DRAM must accommodate DRAM current spikes on VREF and
internal DRAM noise coupled to VREF , both of which may result in VREF noise. VREF should be de-coupled with an
inductance of £ 3nH.
2. VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set
equal to VREF, and must track variations in the DC level of VREF
3. VID is the magnitude of the difference between the input level on CK and the input level on CK.
4. These parameters should be tested at the pin on actual components and may be checked at either the pin or the
pad in simulation. The AC and DC input specifications are relative to a VREF envelop that has been bandwidth limited
to 200MHZ.
5. The value of VIX is expected to equal 0.5*VDDQ of the transmitting device and must track variations in the dc level of
the same.
6. These charactericteristics obey the SSTL-2 class II standards.
