TCXO Specification
CFPT-9008
ISSUE 13; April 2016
Description
Sub 1ppm performance TCXO, a single chip oscillator and
analogue compensation circuit operating over an extended
temperature range. Its ability to function down to a supply
voltage of 2.4V and low power consumption make it
particularly suitable for mobile applications.
-1A No ref voltage, ageing adj option
-1B No ref voltage, no freq adj option
-2A Ref voltage = 2.2V, ageing adj option
-3A Ref voltage = 2.7V, ageing adj option

Supply Voltage
Supply Current: 1+Frequency(MHz)
*1.2*{Load(pF)+30}*10–3mA
Supply voltages in the range 2.4V to 6.0V available to order,
please contact our sales offices
Optional reference voltage output on pad 1, 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
Maximum load current (mA) = Vref/10
For manual frequency adjustment connect an external 50kΩ
potentiometer between pad 1 (Reference Voltage) and pad 4
(GND) with wiper connected to pad 10 (Voltage Control).
Please specify reference voltage as part of the ordering code.

Frequency Adjustment
Three options with external Voltage Control applied to pad 10:
A. Ageing Adjustment:
>±5ppm, frequency <20MHz
>±7ppm, frequency >20MHz
B. No frequency adjustment initial calibration @ 25°C <
±1.0ppm
C. High Pulling ±10ppm to ±50ppm can be available
depending on frequency and stability options (please contact
our sales offices)

Output Details
Output Compatability
Load: 10kΩ // 10pF, AC-coupled
Clipped Sine
Output Control
Tri-state Operation:
Logic ‘1’ (>60% Vs) to pad 8 enables output
Logic ‘0’ (<20% Vs) to pad 8 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)
Output Levels
Vpk-pk > 0.8V
