Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded.
Functional operation should be restricted to recommended operating condition.
Exposure to higher than recommended voltage for extended periods of time could affect device reliability.
Note :
Power & DC Operating Conditions (SSTL_2 In/Out)
Notes
1. Includes
±
25mV margin for DC offset on V
REF
, and a combined total of
±
50mV margin for all AC noise and DC offset on V
REF
,
bandwidth limited to 20MHz. The DRAM must accommodate DRAM current spikes on V
REF
and internal DRAM noise coupled
TO V
REF
, both of which may result in V
REF
noise. V
REF
should be de-coupled with an inductance of
≤
3nH.
2.V
TT
is not applied directly to the device. V
TT
is a system supply for signal termination resistors, is expected to be set equal to
V
REF
, and must track variations in the DC level of V
REF
3. V
ID
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.
