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.

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. 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.
