The ECS-TXO-2520MV-400-AN-TR is a 40.000 MHz Temperature Compensated Crystal Oscillator (TCXO) designed for high-stability timing. It provides a tight frequency stability of ±2.5 ppm over a wide industrial operating temperature range of -40°C to +85°C. This oscillator incorporates MultiVolt™ technology, allowing it to function with an input voltage from +1.7V to +3.6VDC. Housed in a compact 2.5 x 2.0 x 0.9 mm ceramic package with a CMOS output, it is ideal for portable and wireless applications where stability is critical.
