The ACR-2.000MHZ-AMMO is a 2.000 MHz precision quartz crystal oscillator from ABRACON that is designed for use in communications, industrial, instrumentation, automotive, and other high-performance applications. This oscillator is capable of extremely low-noise operation and has a low aging rate of ±3ppm per year. It features a fundamental mode quartz crystal along with a Hybrid Thick Film (HTF) or Surface Acoustic Wave (SAW) resonator, depending on the frequency and operating temperature range. The ACR-2.000MHZ-AMMO also features tight frequency tolerance down to ±10ppm and an operation temperature range of -40 to +85°C. It is packaged in a hermetically sealed, metal 4-pad, 9.5 x 6.5 x 2.5mm package.
