Description
Features:
Miniature 5.0 x7.0mm Surface Mount Package
3.3V Operation
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 +/-4.6ppm accuracies for twenty
years.
