CFPT-9008 Datasheet, PDF (1/3 Pages) IQD Frequency Products Ltd – TCXO Specification

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
Frequency Parameters
Frequency
Frequency Stability
Ageing
10.0MHz to 40.0MHz
±0.30ppm to ±2.50ppm
±2ppm max in 1st year
Electrical Parameters
Supply Voltage
3.3V ±10%
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)
Linearity: <1%
Slope: Positive
Input Resistance: >100kΩ
Modulation Bandwidth: >2kHz
Voltage Control Range:
Without reference voltage: 1.65V±1V
With reference voltage: Vc = 0V to Vref
Ageing:
±1ppm maximum in 1st year, frequency <20MHz
±3ppm maximum for 10 years (including the 1st year),
frequency <20MHz
±2ppm maximum in 1st year, frequency ≥20MHz
±5ppm maximum for 10 years (including the 1st year),
frequency ≥20MHz
After Reflow: ±1ppm max
