Notes:
1. Input frequency is limited by output frequency range and input to output frequency multiplication factor (which is determined by circuit configuration).
2. Longer input rise and fall time will degrade skew and jitter performance.
3. All AC specifications are measured with a 50Ω transmission line, load terminated with 50Ω to 1.4V.
4. Skew is measured at 1.4V on rising edges.
5. Duty cycle is measured at 1.4V.
6. Jitter is measured on 133-MHz signal at 1.4V, low frequency jitter = 350 ps.
7. Duty cycle is measured at 1.4V, 120 MHz.
8. Duty cycle at 133 MHz is 35/65 worst case.
