Notes:
1. Initial calibration @ 25°C. ±2°C, for VCTCXO's Vc = 1.65V. Specifications at time of shipment after 48 hours of operation.
2. Frequency stability vs. change in temperature. [±(Fmax-Fmin)/2.Fo]. For VCTCXO's - Vc -= 1.65V
3. Inclusive of frequency stability, supply voltage change (±1%), aging, for 24 hours.
4. Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25°C
5. Two consecutive solder reflows after 1 hour recovery @ 25°C.
6. Frequency drift over 1 year @ 25°C.
7. BW = 12 KHz to 20 MHz
8. Leave Pad 8 on the TB Series unconnected if enable / disable function is not required. When tri-stated, the output stage is
disabled but the oscillator and compensation circuit are still active (current consumption < 1 mA).
8. Attention: To achieve optimal frequency stability, and in some cases to meet the specification stated on this data sheet,
it is required that the circuit connected to this TCXO output must have the equivalent input capacitance that is specified
by the nominal load capacitance. Deviations from the nominal load capacitance will have a graduated effect on the stability of
approximately 20 ppb per pF load difference..
