CFPT9050
-------
SMD Temperature Compensated Voltage Controlled Crystal Oscillator (PLUTO)
-------
-------
A highly versatile series of surface mountable 14.7 x 9.2 x 6.2 mm Temperature
Compensated Voltage Controlled Crystal Oscillators (TCVCXOs) for applications where
small size and high performance are prerequisites.
-------
Product description
-------
This CFPT9050 uses Rakon's proprietary ASIC 'Pluto™', a single chip oscillator and analogue
compensation circuit, capable of sub 0.3ppm performance. Its wide frequency range,
operating temperature range, drive capability, coupled with its high stability and linear
frequency pulling, make it the ideal reference oscillator. Its ability to function down to a
supply voltage of 2.4 volts and low power consumption makes it particulary suitable for
mobile applications.
