TCXO / VCTCXO
Models DOT050F / DOT050V
Description:
The Connor-Winfield's DOT050F / DOT050V
are Surface Mount, 9x14mm, 3.3V, LVCMOS
Temperature Compensated Crystal Oscillator
(TCXO / VCTCXO) designed for applications
requiring very tight frequency stability and
low phase noise. The RoHS compliant true
surface mount package is designed for high-
density mounting and is optimum for mass
production.
Features:
TCXO Model: DOT050F
VCTCXO Model: DOT050V
• 3.3 Vdc Operation
• Frequency Stability: ±50 ppb
• Temperature Range: 0 to 70°C
• LVCMOS Output Logic
• 9x14mm SMT Package
• Tape and Reel Packaging

Absolute Ratings: Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the
device. These are stress ratings only. The functional operation of the device at those or any other conditions beyond those
indicated under "recommended operating conditions" is not implied. Exposure to conditions outside the "recommended
operating conditions" for any extended period of time may adversely impact device reliability and result in failures not
covered by warranty.

Notes:
1. Frequency referenced to Fo @ 25°C, for VCTCXO models Vc = 1.65V
2. Frequency stability vs. change in temperature. [±(Fmax - Fmin)/(2*Fo)].
3. After 30 days of operation.
4. Inclusive of calibration @25°C, frequency vs. change in temperature, change in supply voltage(±5%), load change(±5%)
and 15 years aging.
5. Referenced to 15 pF.
