Product Description
The FR Series voltage controlled crystal oscillator
achieves wide pullability over a broad range
of operating conditions and frequencies. The
device is constructed with a hermetically sealed,
quartz crystal resonator and low noise clock
IC. The device, available on tape and reel, is
contained in a 7.0 x 5.0mm ceramic package.
Part Ordering Information:
FR XXX YYYY
Applications
The FR 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,
such as:
• SD/HD Video decoding
• SONET/SDH timing control and line cards
• T3/E3 Platforms
• Satellite and microwave communications
• Wireless base stations
• xDSL and DSLAM
• VoIP
