Product Overview
The Epson TG2016SMN / TG2520SMN series are high-stability, low-phase noise Temperature Compensated Crystal Oscillators (TCXOs). These devices utilize an Epson-developed IC and MHz fundamental crystal to deliver superior performance. They are designed for applications requiring precise frequency control and low phase noise, such as GNSS receivers, RF systems, and various wireless communication devices including LTE, WiMAX, Wi-Fi, W-LAN, and IoT devices. The series offers excellent frequency stability over a wide temperature range and boasts the lowest phase noise among Epson's compact TCXO product lineup, making them ideal reference clocks for demanding applications.
