DESCRIPTION
The PL586-15/-18 is a non-multiplier VCXO IC specifically designed to pull fundamental mode crystals from 75MHz to 125MHz. This IC achieves a typical pull range of ±125ppm with 5% linearity. The phase noise performance, with <120fs 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.
