Crystal Oscillator

Crystal Oscillator
Model Name NT2520SB
Temperature-Compensated Crystal Oscillator (TCXO)
NT2520S 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. 0.9 mm, 0.004
cm3, and 0.014 g, respectively.
● A surface-mount crystal oscillator. (Reflow soldering is possible.)
● Lead-free. Meets the requirements for re-flow profiling using lead-free solder.
● Products with the AFC (Automatic Frequency Control) function or Enable/ Disable
function is available.
