Electrical Characteristics - Skew and Differential Jitter Parameters
T
NOTES:
1. Measured into fixed 2 pF load cap. Input to output skew is measured at the first output edge following the corresponding input.
2. Measured from differential cross-point to differential cross-point
3. All Bypass Mode Input-to-Output specs refer to the timing between an input edge and the specific output edge created by it.
4. This parameter is deterministic for a given device
5. Measured with scope averaging on to find mean value.
6. Long-term variation from nominal of input-to-output skew over temperature and voltage for a single device.
7. This parameter is measured at the outputs of two separate ICS9FG1900 devices driven by a single CK410B. The ICS9FG1900's must be set to high
bandwidth. Differential phase jitter is the accumulation of the phase jitter not shared by the outputs (eg. not including the affects of spread spectrum). Target
ranges of consideration are agents with BW of 1-22Mhz and 11-33Mhz.
8. t is the period of the input clock
9. Differential spread spectrum tracking error is the difference in spread spectrum tracking between two ICS9FG1900 devices This parameter is measured at
the outputs of two separate ICS9FG1900 devices driven by a single CK410B in Spread Spectrum mode. The ICS9FG1900's must be set to high bandwidth.
The spread spectrum characteristics are: maximum of 0.5%, 30-33KHz modulation frequency, linear profile.
10. This parameter is an absolute value. It is not a double-sided figure.
