3.3V LOW SKEW CMOS PLL CLOCK DRIVER WITH INTEGRATED LOOP FILTER
NOTES:
1.
See Test Loads and Waveforms for test load and termination.
2.
Skew specifications apply under identical environments (loading, temperature, VDD, device speed grade).
3.
Measured in open loop mode PLL_EN = 0.
4.
Jitter is characterized with Q output at 20MHz. See Frequency Selection Table for information on proper FREQ_SEL level for specified input frequencies.
5.
Skew measured at selected synchronization edge.
6.
tPD measured at device inputs at 0.5VDD, Q output at 80MHz.

See Output Frequency and Frequency Selection tables for more detail on allowable SYNC input frequencies for different speed grades with different FEEDBACK and
FREQ_SEL combinations.
2.
Where pulse witdh implied by DH is less than tWPC limit, tWPC limit applies
