Crystal Oscillator
Temperature Compensated Crystal Oscillator(TCXO)
with wide temperature range for high-precision GPS
NT2520SE
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 +1.68V to +3.63V. Standard specification : +1.8V)
● 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.
