5x7mm
Precision TCXO
Model D75J
Description:
Features:
• 3.3 Vdc Operation
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 of 2
1. Initial calibration @ 25°C. Specifications at time of shipment after 48 hours of operation.
2. Frequency stability vs. change in temperature. [± ±Fmaꢀ ꢁ Fminꢂ)±2ꢃFoꢂ].
3. Frequency change after reciprocal temperature ramped over the operating range.
Frequency measured before and after at 25°C.
5. Output is enabled with no connection to Pad 8. Leave Pad 8 open if disable
function is not required. When disabled, the output is off but the oscillator and
compensation circuits are still powered ±current consumption < 1.3 mAꢂ.
6. For best performance it is recommended that the circuit connected to this output
should have an equivalent input capacitance of 15pF.
