Example: D32G-016.368M-T Bulletin Page Revision Date TX240 1 of 2 04 03 Nov 2011 Notes: 1. Initial calibration @ 25C. Specifications at time of shipment after 48 hours of operation. 2. 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 25C. 4. Within two hours after reflow 5. BW = 12 KHz to 20 MHz. 6. Output is DC coupled. 7. For best performance it is recommended that the circuit connected to this output should have an equivalent input capacitance of 10pF. Specifications subject to change without notice.
