The RTC-4574SA:B PURE SN is a part of a Real Time Clock (RTC) family of integrated circuit products manufactured by Ralecom Electronics. The device is bu ilt using a combination of CMOS, TTL, and memory technologies. It is designed to provide long-term timekeeping accuracy in industrial, military, and aerospace applications where high reliability, long-term stability, and low power consumption are key design considerations. Ralecom Electronics is well known for its commitment to high-reliability, high-performance products.

The RTC-4574SA:B PURE SN provides accurate timekeeping across a wide range of temperatures, from -55 to 125 Celcius. It is designed to operate from 12V to 5.5V and has an accuracy of up to 100ppm over that range. It offers an integrated low-power expander, enabling simple and efficient expansion of the clock for additional capacity. The device also supports an external crystal for higher accuracy applications, allowing for accuracy down to as low as 1ppm.

The device offers several different modes of operation, which are configured by the user. These include run, stop, waiting (interval timer function), programmable alarms and periodic interrupts, as well as a full self-test and watchdog functionality. The RTC-4574SA:B PURE SN is also available with an on-board lithium battery, allowing it to retain its timekeeping and register values during power failures and extended periods of non-use.

The RTC-4574SA:B PURE SN operates according to the Phase-Locked Loop (PLL) principle. This principle is based on an oscillator that is driven by an electronic control circuit. The oscillator is driven by two different signals, one that sets the frequency of the oscillator (the “reference signal”) and one that senses the phase shift in the oscillator’s output (the “error signal”). When the phase differences between the two signals reach a minimum, the oscillator is said to be phase locked and the output is a highly accurate, stable, and repeatable clock frequency.

The RTC-4574SA:B PURE SN can be used in a wide variety of applications involving timekeeping, including time and frequency measurements, clock and data synchronizations, and time stamping. It can be used in a range of industrial, consumer, medical, aerospace and defense applications. Its low power consumption, wide temperature range and quality construction make it well suited for these applications.

The RTC-4574SA:B PURE SN is an ideal choice for applications requiring a high degree of accuracy and reliability. Its combination of PLL-based timekeeping and on-board lithium battery make it one of the most reliable and accurate real-time clocks currently available. Its range of features and functions make it an attractive option for many different types of applications.
