Description:

The Connor-Winfield's TX914

Sinewave Series of Temperature

Compensated Crystal Oscillators

and Voltage Controlled Temperature

Compensated Crystal Oscillators are

designed for use in S3 Telecom Applications. Through

the use of Analog Temperature Compensation, this

device is capable of holding sub 1-ppm stabilities over

the commercial or the industrial temperature ranges.

All models will meet ±4.6 ppm accuracies for twenty

years. STRATUM 3 compliant models are available.

The TX914 series provides temperature stabilities

in the range of ±0.28 ppm to ±2.50 ppm, over the

commercial, extended commercial or the industrial

temperature range.

The TX914 series is available with Sinewave output

along optional Electronic Frequency Tuning (VCTCXO).

These oscillators provide outstanding phase noise

characteristics that will meet the most stringent

requirements.

Notes

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.
