NOTES:
1.
Refers to transition of non-inverting output.
2.
Static phase offset does not include jitter.
3.
t(
φ) is measured with input clock slew rate tSLR(I) = 2V/ns and an input differential voltage VID of 1.75V.
4.
The SSC requirements meet the Intel PC100 SDRAM Registered DIMM specification.
5.
VOX is specified at the SDRAM clock input or test load.
