Phone: 630-851-4722  
Fax: 630-851-5040  
Temperature Compensated  
Crystal Controlled Oscillators  
(TCXO) with a clipped  
sinewave output. Through the use of  
Analog Temperature Compensation,  
the D75AS is capable of holding sub  
0.25-ppm stabilities over the 0 to  
70°C temperature range.

Note:  
1) Initial calibration @ 25 C. Specifications at time of shipment after 48 hours of operation  
2) Frequency stability vs. change in temperature.  
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) Inclusive of calibration @ 25 C, frequency vs. change in temperature, change in supply voltage ( 5%), load  
change ( 5%), reflow soldering process and 20 years aging, referenced to Fo.  
6) 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).  
7) Output is AC coupled.

8) For best performance it is recommended that the circuit connected to this output should have an equivalent  
input capacitance of 10pF.
