Attention: Permanent device damage may occur if “Absolute Maximum Ratings” are exceeded. Functional
operation should be restricted to recommended operation conditions. Exceeding only one of
these values for extended periods of time affect device reliability and may cause irreversible
damage to the integrated circuit.

4)
—
1) DDR400 conditions apply for all clock frequencies above 166 MHz
2) Under all conditions, V_DDQ must be less than or equal to V_DD.
3) Peak to peak AC noise on V_REF may not exceed ± 2% V_{REF (DC)}. V_REF is also expected to track noise variations in V_DDQ.
4) V_TT of the transmitting device must track V_REF of the receiving device.
