Miniaturized TCXOs combine small size with exceptional performance, making them perfect for applications where space is limited but timing accuracy is still critical. These oscillators utilize advanced manufacturing techniques to integrate high-quality crystal resonators and compensation circuits into tiny packages, sometimes as small as 2.5×2.0 mm. Despite their compact size, they maintain stability within ±2.0 ppm or better, ensuring reliable operation in wearable devices, IoT sensors, and portable electronics.
