§ The tsk(o) specification is only valid for equal loading of all outputs.
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 â 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 â¦/ 30 pf load for output swing of 04. V to 2 V.
9. 64 MB DIMM configuration according to PC SDRAM Registered DIMM Design Support Document, Figure 20 and Table 13.
