CFPT9300
------SMD Temperature Compensated Crystal Oscillator (PLUTO)
-------------
A series of lead free surface mountable TCXO/TCVCXO for medium to high volume
applications where small size (5 x 3.2 mm) and high performance are prerequisites.
-------
Product
description
------The CFPT9300 uses Rakon's proprietary ASIC 'Pluto™', a single chip oscillator and analogue
compensation circuit, capable of sub 0.3ppm performance over an extented temperature
range. Its ability to function down to a supply voltage of 2.4V and low power consumption
makes it particulary suitable for mobile applications.
