Clock/Timing - Real Time Clocks : 1418 Products

Real-time clocks provide time and/or date information in almost any electronic device that is needed to keep accurate time. They can provide accurate real-time time for people, or provide accurate time reference for electronic system. At present, most real-time clock chips use crystal oscillator with high precision as clock source.
