CX2119A Low phase noise Crystal Oscillators

Low phase noise Crystal Oscillators

The CX2119A is a low-phase-noise, 10MHz oven-controlled crystal oscillator housed in a standard 36×27mm package. It operates stably in environments ranging from –20°C to +70°C, has an aging rate better than 5E-10/day, and offers excellent near-end and far-end phase noise performance. This product is ideal for use in low-phase-noise phase-locked loop (PLL) local oscillator circuits. When connected to an atomic clock, it significantly improves the system's short-term frequency stability and phase noise performance, while effectively suppressing and eliminating clutter interference from the atomic clock.
