Overview The LA1654C time code reception IC receives long-wave time standard broadcasts (such as the Japanese JJY and German DCF77 standards) and detects and outputs the time code superposed on the long-wave signal. Applications can automatically correct their clocks time setting by using the time code received by the LA1654C. Note that the LA1654C is a bare chip product that is not packaged. Features • Low-voltage operation (operating VCC as low as 1.5V). • Standby mode current drain less than or equal to 0.05µA. Japan : JJY 40/60kHz Germany : DCF77 77.5kHz Functions • RF amplifier, rectifier, detector, time code output, and standby circuit.
