The Connor-Winfield 2.5x3.2mm
Temperature Compensated Crystal
Oscillators and Voltage Controlled
Temperature Compensated Crystal
Oscillators are designed for use in GPS
applications requiring tight frequency
stability over the -30 to 85°C or
-40 to 85°C temperature range.
Through the use of Analog Temperature
Compensation, this device is capable of
holding sub 1-ppm stabilities over the wide
temperature range.
