CFPT9000
-------
SMD Temperature Compensated Crystal Oscillator (PLUTO).
-------
-------
A series of surface mountable 7.0x5.0mm Temperature Compensated Voltage
Controlled Crystal Oscillators (TCVCXOs) for medium to high volume applications where
small size and high performance are prerequisites.
-------
Product description
-------
The CFPT9000 uses Rakon's proprietary ASIC 'Pluto™', a single chip oscillator and analogue
compensation circuit, capable of sub 0.3ppm performance over an extended 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.

NOTES
Parameter
Note 1
Note 2
Description
Frequency range available dependent on output type. HCMOS: 1.25-40MHz, sinewave: 10-
40MHz, clipped sinewave: 10-40MHz.
The tristate control (enable) pin has a internal 100kΩ pull up resistor which allows the pin to
be left unconnected if not required. When in Tri-state mode, the output stage is disabled, but
the oscillator and compensation circuit are still active (current consumption typ.
≤
1.0mA). A
version where voltage control (pad 10) is replaced with tri-state control is available upon
request - please contact the sales office: sales@rakon.com
Higher pulling may be available as a custom option depending on nominal frequency and
stabililty - please contact the sales office: sales@rakon.com
