DESCRIPTION
The PL586-55/-58 is a non-multiplier VCXO IC
specifically designed to pull fundamental mode
crystals from 150MHz to 160MHz. This IC achieves
a typical pull range of ±100ppm with <5% linearity.
The phase noise performance is optimized for
close-in performance and with <100fs phase jitter,
makes this an ideal solution for all high end
clocking applications such as SONET, WiMax,
CPRI, OBSAI, Fiber Channel, and any application
where performance and quality are required.
