Features:
Model: D75J
The Connor-Winfield’s D75J is a 5x7mm
Surface Mount Temperature Compensated
Crystal Controlled Oscillator (TCXO) with
a Tri-State LVCMOS output. Through the
use of Analog Temperature Compensation,
the D75J is capable of holding sub 1-ppm
stabilities over the 0 to 70°C temperature
range.

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. 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.

Attention: To achieve optimal frequency stability, and in some cases to meet the specification stated on this data
sheet, it is required that the circuit connected to this TCXO output must have the equivalent input capacitance
that is specified by the nominal load capacitance. Deviations from the nominal load capacitance will have a
graduated effect on the stability of approximately 20 ppb per pF load difference.
