Crystal Oscillator NEW
Model Name NT2520SB Temperature-Compensated Crystal Oscillator (TCXO) NT2520S Series (with high-precision GPS supported)
n Main Application
For mobile terminals with high-precision GPS functions
l A crystal oscillator with highly stable frequency / temperature characteristics best
suited for GPS.
l Supports low power supply voltage. (Supports DC +1.8 V±0.1 V to +3.2 V±0.1 V.)
l Ultra-compact and light with a height, cubic volume, and weight of Max. 0.9 mm,
0.004 cm3, and 0.014 g, respectively.
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.

Long-term frequency stability
• 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 range, 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.
