In base stations, TCXOs ensure precise synchronization of multiple transceivers, enabling efficient channel allocation and reducing interference. In routers and switches, they provide the timing references needed for packet switching and quality of service (QoS) management. For mobile devices, they support the operation of communication chips, GPS modules, and RF front-ends, ensuring reliable connectivity and signal quality. In satellite communication systems, TCXOs help maintain accurate timing for signal modulation and demodulation, ensuring reliable data transmission over long distances.
