BQ4802LYDWRG4

The BQ4802LYDWRG4 is an RTC (Real Time Clock) device with a wide range of applications and easily handles multiple frequency domains. It is one of the most popular clock devices in the Timing and Clock category and has the capability to provide accurate timekeeping for multiple clock signals at the same time. The device also offers great flexibility for time tracking and applications requiring frequent time updates.

It is used in embedded systems, digital cameras, and cellular devices, among others. The BQ4802LYDWRG4 is designed to generate precise time and date information, including the leap year correction. It supports multiple input clock frequencies, providing the need to make accurate measurements of time intervals over long periods of time.

The device is powered by a 3V lithium battery, making it a low-power and energy-efficient choice for most low-power applications. It provides a high-resolution real-time clock with a wide range of functionality, including alarm management, interrupt source, clock synchronization, and power management. The power management feature allows the device to remain active in low-power operations such as standby and hibernate modes.

The device is capable of outputting up to four separate clock signals, which can be used to drive a range of digital systems and applications. Although primarily used for timekeeping, the BQ4802LYDWRG4 also includes a precise time counter for precise time tracking and measurement. Its ability to generate multiple high-frequency clock signals ensures that high accuracy and stability are maintained.

The BQ4802LYDWRG4 includes an internal clock prescaler which divides the frequency of the input clock by a user-defined value and provides the divided frequency as output clock. This allows the device to generate two or more clock signals which follow the same frequency but are slightly out of phase, effectively doubling the clock rate. This feature is commonly used in complex systems and microcontrollers to reduce EMI noise.

The BQ4802LYDWRG4 is a reliable and intuitive device with a wide range of applications. It is designed to meet the needs of a wide range of applications, including automotive, industrial, medical, and consumer applications. With its low-power and energy-efficient architecture and its wide range of features, the BQ4802LYDWRG4 is an ideal choice for timekeeping applications.
