Oscillators Oscillators are electronic circuits that generate a periodically varying waveform, usually a sine wave, whose frequency and phase can be precisely controlled. Such waves can be used to time, control, or frequency-divide circuits. The CE3391-32.768 performs frequency-division applications for a wide variety of hardware and software applications, including digital clocks, timing systems, and electro-mechanical systems.The CE3391-32.768 is a high-precision, low-power digital 32.768 kHz oscillator that is used to accurately and precisely time and divide high-frequency clock signals. This oscillator uses a CMOS inverter-based crystal oscillator which is controlled by an on-chip oscillator-resistor network and operated with an external 32.768 kHz quartz crystal. It has a wide frequency range of 15.6 kHz to 99.3 kHz, and it delivers a ±20 ppm (parts per million) frequency deviation from the optimal 32.768 kHz frequency. The very low power consumption of the device, along with its low frequency deviation make it an ideal choice for applications that require an accurate and stable frequency over a wide range of operating conditions.The CE3391-32.768 uses crystal oscillator technology to generate a steady 32.768 kHz frequency. The device consists of an on-chip oscillator-resistor network, which is used to control the oscillator frequency, and an external 32.768 kHz quartz crystal, which is used to provide the necessary reference frequency. The oscillator frequency is determined by the on-chip resistor network, and this is further adjusted by a precision external resistor. The external resistor is used to fine-tune the frequency of the oscillator to the nearest Hertz.The CE3391-32.768 uses a quiescent current of only 2 μA (microamps). This can be reduced to less than 1 mA (milliamp) when the device is in sleep mode. The device also operates from a voltage ranging from 1.8V to 3V, with a maximum current draw of only 15 mA.The CE3391-32.768 is designed for use with high-speed digital logic systems, such as microcontrollers, clocks, timers, etc. It can be used to precisely divide a clock signal into smaller pulses, allowing these pulses to be used to time, control, or frequency-divide circuits. The device can also be used to accurately measure time intervals, such as microseconds, and is suitable for applications that require low power consumption.In summary, the CE3391-32.768 oscillator is a highly accurate and low-power oscillator that is suitable for a wide range of timing, control, and frequency-division applications. It is designed to the highest standard, and is capable of delivering a very low power consumption and precise frequency. The device is also suitable for applications that require a wide operating range, and is capable of delivering a very precise frequency tolerance.
