Note:
11. Parameters are guaranteed by design and characterization. Not 100% tested in production.
12. PLL is capable of meeting the specified parameters while supporting SSC synthesizers with modulation frequency between 30 kHz and 33.3 kHz with a down
spread of –0.5%.
13. While the pulse skew is almost constant over frequency, the duty cycle error increases at higher frequencies. This is due to the formula: duty cycle = tWH/tC, where
the cycle time (tC) decreases as the frequency goes up.
14. Refers to transition of non-inverting output.
15. Period Jitter and Half-Period Jitter specifications are separate specifications that must be met independently of each other.
16. All differential input and output terminals are terminated with 120
/16 pF as shown in Figure 6.
17. DUT refers to Device Under Test.
