DESCRIPTION
The PLL600-27M is part of PhaseLink ’s low cost
family of XO IC’s, designed to replace multiple XO
solutions saving the cost and board space of clock
distribution buffers. In addition, this product family
provides among the lowest current on the market for
the 10MHz to 52MHz range. They accept input
crystals from 10MHz to 52MHz (fundamental
resonant mode) and provide low phase noise (<-
130dBc at 10kHz offset at 30MHz), and very low
jitter (2.5 ps RMS period jitter) outputs.
