Timing solutions are critical to today’s electronics. Many engineers rely on the internal real-time clock (RTC) functionality that comes embedded in microcontroller units (MCUs) and system on chips (SoCs). Those functions rely on crystal, crystal oscillator (XO), and temperature compensated crystal oscillator (TCXO) options as external frequency sources that translate into system clocks, which then determine the accuracy of the RTC function. In some cases, it may be more beneficial to use RTC module timing solutions instead.
This paper lays out the barriers and benefits of various timing solutions and offers guidance on when and why an RTC module timing solution may be a better choice and outlines the specific benefits of choosing Epson RTC module timing solutions.
