Description
Features
The Connor-Winfield’s D75AS
is a 5x7mm Surface Mount
Temperature Compensated
D7250A.0SM0H8z47
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.

Initial calibration @ 25 C. Specifications at time of shipment after 48 hours of operation
Frequency stability vs. change in temperature.
Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before
and after at 25°C.
Within two hours after reflow.
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.
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).
Output is AC coupled.
For best performance it is recommended that the circuit connected to this output should have an equivalent
input capacitance of 10pF.
