It provides \u00b110 ppm frequency tolerance at 25\u00b0C and \u00b120 ppm stability over the -40\u00b0C to +125\u00b0C automotive temperature range. With 8pF load capacitance and 30\u03a9 max ESR, it is designed for low-power oscillator circuits in automotive MCU, wireless radio, and Ethernet PHY clock generation applications.","working_principle":"The DSX321G uses AT-cut quartz crystal operating in thickness shear mode. The AT-cut provides excellent frequency stability over a wide temperature range with a cubic turnover characteristic. At 40MHz, the crystal vibrates at its fundamental (or 3rd overtone) resonant frequency determined by the quartz blank thickness. The equivalent circuit consists of a series RLC branch (motional arm) in parallel with a shunt capacitance C0. The low 8pF load capacitance is optimized for modern low-power oscillator designs.","pin_description":"
