LOW SKEW CMOS PLL CLOCK DRIVER WITH INTEGRATED LOOP FILTER
NOTE:
1. Operation in the specified SYNC frequency range guarantees that the VCO will operate in its optimal range of 28MHz to F
MAX_Q
x2. Operation with
Sync inputs outside specified frequency ranges may result in out-of-lock outputs. FREQ_SEL only affects VCO frequency and does not affect output
frequencies.
