COMMERCIAL TEMPERATURE RANGE
1. This skew represents the absolute output clock skew and contains the pad skew and package skew (See “Clock Output (Yn) Skew”). This
parameter is specified for the clock pairs on each side of the register independently. The skew is applicable to left side clock pairs between
Y0/Y0 and Y2/Y2, as well as right side of the clock pairs between Y1/Y1 and Y3/Y3. This is not a tested parameter and has to be considered
as a design goal only.
2. This skew represents the absolute Qn skew compared to the output clock (Yn), and contains the register pad skew, clock skew and package
routing skew (See “Qn Output Skew for Standard 1/2-Clock Pre-Launch”). The output clock jitter is not included in this skew. The Qn
output can either be early or late. This parameter applies to each side of the register independently. The parameter includes the skew related
to simultaneous switching noise (SSO).
3. The parameter is a measure of the output clock pulse width HIGH/LOW. The output clock duty cycle can be calculated based on tPW.
4. This skew represents the absolute Qn skew compared to the output clock (Yn), and contains the register pad skew, clock skew and package
routing skew (See “Qn Output Skew for Standard 3/4-Clock Pre-Launch”). The output clock jitter is not included in this skew. The Qn
output can either be early or late. This parameter applies to each side of the register independently. The parameter includes the skew related
to simultaneous switching noise (SSO).
5. This parameter measures the delay from the rising differential input clock which samples incoming C/A to the rising differential output
clock that will be used to sample the same C/A data. tSTAOFF may vary by the amount of tDYNOFF based on voltage and temperature drift as
well as tracking error and jitter. Including this variation tSTAOFF may not exceed the limits set by tSTAOFF(MIN) and tSTAOFF(MAX).
6. See “Measurement Requirement for tSTAOFF and tDYNOFF“.
7. Implies a -3 dB bandwidth and jitter peaking of 3 dB.
