SMD Temperature Compensated Crystal Oscillator
-------
-------
SMD Temperature Compensated Crystal Oscillator for Stratum 3 applications.
-------
Product description
-------
The RFPT500 is based on Rakon's patented Pluto™ TCXO technology delivering industry
leading performance. Tailored specifically to the requirements of Stratum 3
telecommunication applications the RFPT500 is a low cost solution which allows the system to
be compliant with Belcore standards GR-253 and GR-1244. The standard package has 10
pads but 4 or 8 pad versions are available on request.
