Applications
The ST1307 Series VCXO is an ideal component
in phase locked loop circuits that perform clock
smoothing, clock/data recovery, or frequency
translation and card synchronization functions,
supporting jitter-sensitive applications such as:
• SMPTE-compliant Video networking
• SONET/SDH timing control and line cards
• T1/E1 Platforms

Product Description
The ST1307 is a voltage controlled crystal oscillator
that achieves superb jitter and pullability over a broad
range of operating conditions and frequencies. The
device is constructed with a hermetically sealed,
fundamental-mode quartz crystal resonator exhibiting a
high-Q for exceptional phase noise performance. The
device, available on tape and reel, is contained in a
5x7mm ceramic package.
