X1286V14T1

The X1286V14T1 is a highly reliable intelligent real-time clock (RTC) with flag signal outputs and a temperature-compensated crystal oscillator (TCXO). It is used in a variety of applications where accuracy and reliability are critical. In addition to the primary functions of calendar, alarm and timer, the X1286V14T1 provides synchronization of multiple devices, power management, and energy-saving features.

Applications

The X1286V14T1 offers time-keeping stability across a wide range of temperature and has been designed for use in industrial RTU (remote terminal units), security systems, smart meters, process control systems, IoT (internet of things) devices and other high-reliability applications. Other applications include the integration of multiple system elements and the synchronization of multiple subsystems.

Features & Benefits

The X1286V14T1 is a highly reliable, low-power real-time clock. It features an on-chip clock generator that can generate a signal at preset intervals to support periodic tasks. Other features include a wide operating voltage range and a high-precision temperature-compensated crystal oscillator (TCXO). The X1286V14T1 also provides flag signal outputs to indicate the status of the device.

Working Principle

The X1286V14T1 is an intelligent real-time clock based on a 32.768 kHz quartz crystal. The quartz crystal oscillates at a constant frequency which is then divided down to 1 Hz by an internal divider circuit. The 1 Hz signal is used to drive the clock and calendar functions and provide the flags for synchronization and other features.

The oscillator is temperature compensated to achieve better accuracy and greater stability over a wide temperature range. The X1286V14T1 also provides a power-saving mode that reduces power consumption to a minimum while still providing accurate timekeeping. This feature allows the device to be used in battery-powered applications.
