SiTime µPower MEMS oscillators are designed specifically for wearable, IoT, and mobile applications, where space and power are critical. They consume up to 90% less power and are up to 80% smaller than quartz oscillators. Plus, they are available in low frequencies that quartz cannot support.
For tuning output frequency by up to ±150,000 ppm, see our Digitally Controlled µPower XO.
The SiT1534 and SiT1569 are the first µPower oscillators capable of a frequency range between 1 Hz and 462.5 kHz in a 1.2 mm2 footprint. In the chip-scale package (CSP), these products reduce a timing device’s footprint by as much as 85% compared to existing 2.0 x 1.2 mm SMD quartz packages. Unlike XTALs, the SiT1534 oscillator output enables greater component placement flexibility and eliminates external load capacitors, thus saving additional component count and board space.
