Smart Watches and Fitness Trackers

Smart Watches and Fitness Trackers

Smartwatches and fitness trackers must be feature-rich, user-friendly, and beautiful. These devices must continually incorporate the latest technology to enable a growing list of functions, while at the same time consume less space and power. Plus, at the end of the day, they need to deliver accurate time with no drift.

SiTime MEMS 32 kHz oscillators provide the solution for smartwatches and activity trackers to win in both form and function – with ultra-small, low-power, high-accuracy timing.
