Product Description
The S1569 is a voltage controlled crystal oscillator that
achieves superb jitter and temperature stability 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
9x14mm FR4 package.
Applications
The S1569 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/DWDM/E4 timing control & line cards
• 1 & 10 Gigabit Ethernet and FibreChannel
• Satellite, microwave and cellular base stations
• Server & Storage platforms
