PIN DESCRIPTION
NOTE:
1. For best accuracy, use parallel resonant crystal specified for a load capacitance
of 15pF.

FUNCTION TABLE
NOTES:
1. Operation in the specified CLKIN frequency range guarantees that the VCO will operate in the optimal range of 25MHz to 160MHz. Operation with CLKIN outside specified
frequency ranges may result in invalid or out-of-lock outputs.
2. Q
[2:0
] is not allowed to be used as feedback.

ABSOLUTE MAX IMUM RATINGS
(1)
NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUMRATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximumrating
conditions for extended periods may affect reliability.
CRY S TAL S PE CIFICAT ION
The crystal oscillators should be fundamental mode quartz crystals:
overtone crystals are not suitable. Crystal frequency should be specified
for parallel resonance with 50
maximumequivalent series resonance.
