1 to 26 MHz, Ultra-Small µPower Oscillator

The SiT8021 is the world's smallest, lowest power and lightest MHz oscillator. It is 90% lower in power consumption and 40% smaller than the smallest quartz oscillator. The unmatched combination of ultra-low power, ultra-small package, and wide frequency range make this device ideal for power-sensitive and space-constrained applications.
