Crystal oscillator

The LTC6930 series is a series of precision silicon oscillators with very low power. (Oscillator English: oscillator is an electronic component used to generate repeated electronic signals. The circuit is called an oscillating circuit. It can convert DC power to a certain frequency. There are many kinds of electronic circuits or devices for electrical signal output, which can be divided into self-excited oscillators and other oscillators according to the oscillation excitation mode, and the frequency error is less than 0.09%. For each oscillator, the user can select one of eight frequencies in the range of 32.768kHz to 8.192MHz. Depending on a fixed main oscillator frequency, the internal divider between 1 and 128 can provide 8 different frequencies. In addition to the power supply bypass capacitor, the LTC6930 does not require additional external components.
The LTC6930 features a proprietary control architecture that enables ultra-low power operation while maintaining industry-leading accuracy and jitter specifications. The excellent fast start-up time, combined with low power consumption, makes the device ideal for battery-powered applications with frequent power-up cycles. The device is shipped from any frequency in the range of 32.768kHz to 8.192MHz.
LTC6930 features: frequency error <0.09%, start-up time <110μs, 1.7V to 5.5V single supply operation, 105μA typical supply current (at 32kHz, V+=3V), 490μA typical supply current (at 8MHz, V+=3V)
Typical RMS (a scheduling algorithm with tasks assigned by monotonic rate priority, called monotonic rate scheduling. RMPA means that the priority of a task is allocated according to the task period T. It determines the scheduling priority according to the length of the execution period of the task, those with Small execution cycle tasks have higher priority, long cycle tasks have lower priority) cycle jitter <0.15% (at V+=3V). Five options cover the frequency range from 32.768kHz to 8.192MHz: LTC6930-4.19: 4.194304MHz÷N; LTC6930-5.00: 5.000000MHz÷N; LTC6930-7.37:7.373800MHz÷N; LTC6930-8.00: 8.000000MHz÷N; LTC6930-8.19: 8.192000MHz÷N; where N=1, 2, 4, 8, 16, 32, 64, 128; -40oC to 125oC operating temperature range; slim 2mm x 3mm DFN or MS8 package
LTC6930 Application: Precision Digitally Controlled Oscillator: Microprocessor Clock: Power Clock: Portable and battery powered devices.
