Description:
The Connor-Winfield
5.0x7.0mm Temperature
Compensated Crystal
Controlled Oscillators
and Voltage Controlled
Temperature Compensated Crystal
Controlled 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
meet +/-4.6 ppm accuracies for twenty
years. Three STRATUM 3 compliant model
series are available.
