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 temperature range. Through
the use of Analog Temperature
Compensation, this device is capable of
holding sub 1-ppm stabilities over the
wide temperature range.
