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 0.2ppm 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 (& ACMOS): 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 tristate mode, the output stage is disabled, but
the oscillator and compensation circuit are still active (current consumption typ.
≤
1.0mA).
Availability of tristate and the tristate control pin number will depend on the outline selected
(P1~P4). Alternative pin configurations may be 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.
