Features
n
l A crystal oscillator with highly stable frequency / temperature characteristics best
suited for GPS.
l Supports low power supply voltage. (Supports DC +2.4 0.1 V to +3.2 0.1 V.)
l Ultra-compact and light with a height, cubic volume, and weight of 0.8 mm max.,
3
0.0035 cm , and 0.013 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.
