LOW SKEW TTL PLL CLOCK DRIVER WITH INTEGRATED LOOP FILTER
NOTES:
1. Operation in the specified SYNC frequency range guarantees that the VCO will operate in its optimal range of 20MHz to F
MAX_2
X
Q
. 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.
2. The lock output pin (LOCK) may not indicate reliably for VCO frequencies below 30MHz.
