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 25°C. 4. BW = 12 KHz to 20 MHz. 5. Leave Pad 8 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). 6. For best performance it is recommended that the circuit connected to this output should have an equivalent input capacitance of 15pF. 2111 Comprehensive Drive Aurora, Illinois 60505 Phone: 630- 851- 4722 Fax: 630- 851- 5040 www.conwin.com Package Layout Suggested Pad Layout 0.079 Max.
