5x7mm
Precision TCXO
Model D75F
Description:
Features:
• 3.3 Vdc Operation
The Connor-Winfield’s D75F 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 D75F
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. [± ±Fmaꢀ ꢁ Fminꢂ)±2ꢃFoꢂꢄ.
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 triꢁstated, the output stage is disabled but the oscillator and compensation circuit are still
active ±current consumption < 1 mAꢂ.
