Crystal Oscillator

Crystal Oscillator
Model Name NT3225SA
Temperature Compensated Crystal Oscillator (TCXO) NT3225S Series
(with high-precision GPS supported)
■ Main Application
For mobile terminals with high-precision GPS functions
■ Features
● A crystal oscillator with highly stable frequency / temperature characteristics best
suited for GPS.
● Supports low power supply voltage. (Supports DC +1.7 V to +3.3 V.)
● Compact and light with a height, cubic volume, and weight of Max. 1.0 mm,
0.007 cm3, and 0.024 g, respectively.
● Low power consumption.
● A surface-mount crystal oscillator. (Reflow soldering is possible.)
● Lead-free. Meets the requirements for re-flow profiling using lead-free solder.
