LSI for Radio Clocks [170KB] PDF

Takayuki Kondo, Katsuya Maruyama, Tsunao Oike

Radio clocks are always able to sustain accurate time, as they are equipped with functions for receiving low frequency signals (standard-time and frequency-signal emission) that carry time information and automatically correct time and calendars. This paper will provide a general summary of radio clocks and the "ML6191", a real-time clock LSI with an automatic time correction function that is a combination of an RF for the standard frequency and a real-time clock in a single chip, a description of application examples and future efforts.
