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, V
DD
, 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.
