low phase noise XO, providing less than -135dBc at
10kHz offset in the 24MHz to 50MHz operating
range. The very low jitter (3ps RMS period jitter)
makes this chip ideal for applications requiring clean
reference frequency sources. Input crystal can range
from 12 to 25MHz (fundamental resonant mode).
