The Connor-Winfield’s D75AS is a 5x7mm
Surface Mount Temperature Compensated
Crystal Controlled Oscillator (TCXO)
with a Tri-State Clipped Sinewave output.
Through the use of Analog Temperature
Compensation, the D75AS is capable
of holding sub 1-ppm stabilities over the
0 to 70°C temperature range.

Ordering Information
D57AS-025.0M*
* For the tape and reel option, add -T to the end of the part number. Example: D75AS-25.0M-T
Notes:
1. Initial calibration @ 25°C. 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. Within two hours after reflow
5. Inclusive of calibration @ 25C, frequency vs. change in temperature, change in supply voltage (±5%), load change (±5%), reflow soldering process and 20 years aging,
referenced to Fo.
6. BW = 12 KHz to 20 MHz.
7. 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).
8. Output is AC coupled.
9. For best performance it is recommended that the circuit connected to this output should have an equivalent input capacitance of 10pF.
