3.2 x 2.5 mm
Precision TCXO
In Stock at Digi-Key
Description:
The Connor-Winfield D32G is a 3.2
x 2.5 mm, 3.3 V Clipped Sinewave,
Surface Mount, Temperature
Compensated Crystal Oscillator
(TCXO) designed for applications
requiring tight frequency stability in
a very small package. The RoHS
compliant surface mount package is
designed for high-density mounting
and is optimum for mass production.

Package Characteristics
Package Hermetically sealed ceramic package and metal cover
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. BW = 12 KHz to 20 MHz.
6. Output is DC coupled. Load capacitor, load resistor, coupling capacitor and by pass capacitors are required components to
insure proper operation of this TCXO.
7. For best performance it is recommended that the circuit connected to this output should have an equivalent input capacitance
of 10pF.
