Crystal Oscillator
NT2520SE
Temperature Compensated Crystal Oscillator(TCXO)
with wide temperature range for high-precision GPS
■ Main Application
Automotive communication(e.g., Automotive navigation or Telematics), Wireless
module, and GPS / GNSS module, etc.
■ Features
● Supports ±0.5×10–6 / -40 to +105°C
● A crystal oscillator with highly stable frequency / temperature characteristics best
suited for GPS.
● Compact and light with a height, cubic volume, and weight of Max. 0.9 mm, 0.004
cm3, and 0.014 g, respectively.
● Supports low power supply voltage. (Supports DC +1.7 V to +3.3 V.)
● 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.
● Conforms to AEC-Q100/200.
● Products with the AFC (Automatic Frequency Control) function is available.
