RoHS compliant lead free. See soldering profile on page 4. Notes: 1. Frequency stability vs. change in temperature [±(Fmax-Fmin)/(2*Fo)], Vc = nominal control voltage for VCTCXO models. 2. Initial calibration @ 25°C, Vc = nominal control voltage for VCTCXO models. Specification at the time of shipment after 48 hours of operation. 3. Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after @ 25°C. 4. For best application performance, careful selection of an external power source is critical. Select an external regulator that meets or exceeds to following specifications regarding voltage regulation tolerance, initial accuracy, temperature coefficient, voltage noise, and low voltage noise density. Factory Test Conditions: Initial Accuracy ±2mv, Noise (0.1Hz to 10 KHz) 15uV p-p, Voltage Noise Density = 50nV/sqrt Hz, Temperature Coefficient < 5ppm/°C. 5. Attention: To achieve the frequency stability specified 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 20ppb per pF load difference. 6. Load capacitor, load resistor, coupling capacitor and by pass capacitors are required components to insure proper operation of this TCXO / VCTCXO. 7. Output is DC coupled.
