Crystal Oscillator
Model Name NT3225SA
Temperature-Compensated Crystal Oscillator (TCXO) NT3225S Series (with high-precision GPS supported)
n Main Application
For mobile terminals with high-precision GPS functions
n Features
l A crystal oscillator with highly stable frequency / temperature characteristics best
suited for GPS.
l Supports low power supply voltage. (Supports DC +2.4 V±0.1 V to +3.5 V± 5 %.)
l Ultra-compact and light with a height, cubic volume, and weight of Max. 1.0 mm,
0.007 cm3, and 0.024 g, respectively.
Pb
Free
l Low power consumption.
l A surface-mount crystal oscillator. (Reflow soldering is possible.)
l Lead-free. Meets the requirements for re-flow profiling using lead-free solder.

• Frequency setting conditions
1. Frequencies are set at normal temperatures (+25±2 °C).
2. Frequencies are set with a printed board that has a
ground pattern attached to the underside of an oscillator.
3. Connect the #1 terminal of the oscillator to the ground
that comes with the oscillator.
• If you require a product with a different frequency, power
supply voltage, frequency control characteristic, etc. to the
standard specifications, please contact us with your
enquiries.
• Products with the AFC (Automatic Frequency Control)
function are available. If you require such a product, please
contact us.
*1. A DC-cut capacitor is not embedded in this crystal
oscillator. Connect a DC-cut capacitor (1,000 pF) to the
line-out terminal of the oscillator.
