Frequency stability vs. change in temperature. [±(Fmax - Fmin)/2.Fo]. 3. Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25°C. 4. Within two hours after reflow 5. BW = 12 KHz to 20 MHz. 6. Output is DC coupled. Load capacitor, load resistor, coupling capacitor and by pass capacitors are required components to insure proper operation of this TCXO. 7. For best performance it is recommended that the circuit connected to this output should have an equivalent input capacitance of 10pF. 2111 Comprehensive Drive Aurora, Illinois 60505 Phone: 630- 851- 4722 Fax: 630- 851- 5040 www.conwin.com Pad Connections Environmental Characteristics Vibration: Vibration per Mil Std 883E Method 2007.3 Test Condition A Shock: Mechanical Shock per Mil Std 883E Method 2002.4 Test Condition B.
