Crystals are essential components in electronic systems. Their main purpose is to provide an accurately determined frequency, voltage or temperature in the circuit. They range in size from a few microns up to several millimeters in diameter. The vast majority of crystals are semiconductor-based, typically made of silicon, although others such as gallium arsenide are also used. The ATS640BSM-1E is a low-profile, leadless, full-wave silicon crystal oscillator. It can be used in a wide variety of applications where a precise and stable frequency reference is required. It is designed to provide a high-accuracy frequency source of 32.768kHz for timekeeping applications, such as real-time clocks, microcontrollers and frequency high-accuracy oscillators.The ATS640BSM-1E is available in two different packages: an SMT LCC package and a leadless SMT package. Both packages provide the same features, but the SMT LCC package is much smaller, making it ideal for space-constrained applications. The ATS640BSM-1E is designed to provide exceptional accuracy and stability as well as low jitter and low power consumption. It has a frequency accuracy of ±1.0 ppm at 25°C over the temperature range of -40°C to 85°C and a total frequency stability of ±1.0 ppm per year at 25°C. The device also features “snap-in” mounting with the use of standard “polishing” of the board, suitable for reflow soldering.The ATS640BSM-1E is an ideal crystal for low power, real-time clock, microcontroller, and frequency sources applications. It is suitable for battery life, such as watches and other timekeeping devices, as well as for any miniature space-constrained applications. Other applications include automotive and avionic systems, measuring and controlling devices, and laboratory instruments.The ATS640BSM-1E works on the principle of settling the internal oscillator at a certain frequency. A signal voltage is applied to the quartz crystal and the inductive element of the oscillator acts as a loading element, allowing the crystal to resonate at its resonant frequency determined by it\'s design (size and shape) and when the signal is cycled, the crystal generates an oscillating output which is then used to measure time with extreme accuracy. The ATS640BSM-1E has a wide range of features that make it ideal for timekeeping applications, such as low power consumption, high temperature stability, and low jitter, as well as a ±1.0ppm frequency accuracy, ±1.0ppm/year total frequency stability, and a wide operating temperature range of -40°C to 85°C. In summary, the ATS640BSM-1E is an ideal solution for low power, miniature, and high-accuracy applications. Its high-reliability and low power consumption make it suitable for battery-powered applications and its superior accuracy, stability, and wide temperature range make it an ideal choice for clock generators, microcontrollers, frequency sources, and timekeeping devices.
