DESCRIPTION
The PLL600-27T/-37T form a low cost family of XO
IC’s, designed to replace multiple XO solutions sav-
ing the cost and board space of clock distribution
buffers. In addition, they provide among the lowest
current on the market for the 10MHz to 52MHz
range. They accept input crystals from 10 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.
