Abracon's series of watch-MEMS® kHz MEMS oscillators feature the world's smallest CSP (1.5 mm x 0.8 mm) and SMD (2.0 mm x 1.2 mm) packages. This series is based on SiTime's proprietary NanoDrive technology. These devices are ideally suited for tuning fork crystal replacement in space-constrained designs. Optimized for the wearable, IoT, and consumer solutions, these devices provide a temperature stabilized alternative to tuning fork crystal-based timing, while eliminating the oscillator loop capacitors, saving significant surface area, complexity, and frequency variation over temperature.
