SiT8021
Ultra-Small, 1 to 26 MHz Oscillator
The Smart Timing Choice
Description
The SiT8021 is the industry's smallest and the lowest power MHz oscillator. With 0.1 mW of active power consumption at 3.072 MHz output frequency, this µPower oscillator enables longer battery life for a wearable, IoT or mobile device compared to a quartz-based oscillator wk.baidu.comr resonator. The device comes in the smallest 1.5 mm x 0.8 mm package. The unique combination of ultra-low power, ultra-small package and flexible output frequency makes it ideal for power sensitive and space constrained applications including:
