CFPT-9050 SMD TCVCXO
iSSUE 8; 1 NOVEMBER 2008 - RoHS 2002/95/EC
Supply Current
Description
0.3ppm TCXO manufactured for us by Rakon utilising their
Pluto™ ASIC technology. Its wide frequency range, operating
temperature range and drive capability coupled with high
stability and linear frequency pulling make it the ideal
reference oscillator. Its ability to function down to a supply
voltage of 2.4V and low power consumption makes it suitable
for mobile applications
14.7 x 9.2mm
9.6, 10, 12.8, 19.44, 20, 38.88, 49.152, 51.84MHz
HCMOS 15pF max
ACMOS 50pF max
Sinewave 10k

Temperature: see table
Typical Supply Voltage Variation ± 10% < ± 0.2 ppm*
Typical Load Coefficient 15pF ± 5pF < ± 0.2 ppm*
*Depending on frequency and output type
HCMOS Typically:
1+ Frequency(MHz)*Supply(V)*{Load(pF)+ 15}*10
–3
mA
eg. 20MHz, 5V, 15pF ≈ 4mA
ACMOS Typically:
1+ Frequency(MHz)*Supply(V)*{Load(pF)+ 23}*10
–3
mA
Sinewave, 6 to 12 mA depending on frequency
Clipped Sinewave, Typically:
1+ Frequency(MHz)*1.2*{Load(pF)+ 30}*10
–3
mA
± 1ppm maximum in first year
± 3ppm maximum for 10 years
± 1ppm maximum after reflow
Optional reference voltage output on Pad 5, suitable for
potentiometer supply or DAC reference.
1. No output (Standard option)
2. 2.2V, for Min. Vs > 2.4V
3. 2.7V, for Min. Vs > 3.0V
4. 4.2V, for Min. Vs > 4.5V
Maximum load current (mA) = Vref/10

Output Compatibility & Load
Reference Voltage, Vref (HCMOS/ACMOS only)
Frequency Stability
Frequency Adjustment
Three options with external Voltage Control applied to Pad 1:
For manual frequency adjustment (HCMOS/ACMOS output
only) connect an external 50kW potentiometer between Pad 5
(Reference Voltage) and Pad 3 (GND) with wiper connected to
Pad 1 (Voltage Control). Please specify reference voltage as a
part of the ordering code.
TCXOs
A - Ageing adjustment: > ± 5ppm (Standard Option)
B - No frequency adjustment. Initial calibration @ 25°C
< ± 0.5 ppm
C - High Pulling ±10ppm to ±50ppm may be available
depending on specification options. Contact our sales office
Linearity <1% (positive slope)
Input resistance >100k
W
Modulation bandwidth >2kHz
Standard control voltage ranges:
Without reference voltage - Vs = 5.0V 2.5V ± 2V
Without reference voltage - Vs = 3.3V 1.65V ± 1V
With reference voltage - Vc = 0V to Vref
–55 to 125°C
Logic ‘1’ (>60%Vs) to Pad 2 enables output
Logic ‘0’ (<20%Vs) to Pad 2 disables output
When at logic ‘0’ the output stage is disabled for all output
options, but the oscillator and compensation circuit are still
active (Current consumption < 1mA)
Standard 3.3V, 5.0V (see table)
Supply voltages in the range 2.4 to 6.0V available to order,
please contact our sales office
Note: Please contact our sales office if a reference voltage is
required in combination with sine or clipped sinewave output
