The X1228S14I-4.5A is a versatile clock/timing product used in a variety of applications. This product is useful for applications where both time and frequency accuracy are required. It is a real-time clock (RTC) device that includes an onboard crystal oscillator with a frequency accuracy of ±20 parts per million (ppm). The device offers multiple clock outputs, including an output frequency selectable between 2.0 and 2.05 MHz. It also has a low-power idle mode that conserves power when the main oscillator is not being used.
The X1228S14I-4.5A is built with a wide range of features that make it suitable for a variety of applications. It has two general-purpose inputs for timing events or for general-purpose alarm functions. It also has a 20-bit data register that can store up to 20 bytes of data. This register is useful for storing time-stamping information and other system parameters.
The X1228S14I-4.5A operates with an on-board 32.768 kHz crystal oscillator and offers multiple outputs at either 0.5 or 1.024 kHz. It also includes an integrated voltage regulator to maintain the output voltage at a stable level. This device features a power-down mode that allows it to quickly enter sleep mode and reduce its power consumption. Additionally, it supports an integrated temperature sensor that can be used to monitor changes in the device’s environment.
The main application for the X1228S14I-4.5A is in providing highly-accurate timekeeping for a variety of applications. This includes applications such as timestamping, alarm systems, and time-of-day operations. The device can also be used to synchronize multiple devices, such as in an audio system in which several devices need to be kept in sync. Furthermore, the device can be used to support communication protocols such as Bluetooth or Wi-Fi.
The working principle of the X1228S14I-4.5A is based on its internal clock/timer. The oscillator inside the device runs at a frequency of 32.768 kHz and generates a rapid stream of pulses that are used to track the passage of time. The frequency accuracy of the pulses is determined by the accuracy of the onboard crystal oscillator. The pulses from the oscillator are used to increment a 16-bit counter that counts the number of 32.768 kHz cycles. This counter is the basis for the accuracy of the clock/timer.
The X1228S14I-4.5A is designed for use in a variety of applications that require precise timekeeping. It can be used as an audio/video synchronization device, a network time server, as an industrial automation clock, and as a clock/calendar generator. It is also suitable for use in medical applications and as a reference time source for communications protocols. This versatile device is capable of providing high-accuracy timing and synchronization for applications needing both time and frequency accuracy.
