TCXO Specification CFPT-9003 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 -4A Ref voltage = 4.7V, ageing adj option Frequency Parameters Frequency Frequency Stability Ageing 10.0MHz to 40.0MHz ±0.30ppm to ±2.50ppm ±2ppm max in 1st year (See Note 2) Outline (mm) -1A = No ref voltage, ageing adj option Electrical Parameters 5.0V ±10% Supply Voltage Supply Current: <8mA 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.
