NOTES: 6. The specifications for parameters in this table are applicable only after any appropriate stabilization time has elapsed.
7. Calculated per PC DRAM SPEC (tphase _error, static − jitter(cycle-to-cycle)).
8. This is equivalent to 0.8 ns/2.5 ns and 0.8 ns/2.7 ns into standard 500 Ω/ 30 pf load for output swing of 04. V to 2 V.
