Time Code Reception IC

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 clock's time setting by using the time code received by the LA1654C.

Note that the LA1654C is a bare chip product that is not packaged.

Function

• RF amplifier, rectifier, detector, time code output, and standby circuit.

Features

• Low-voltage operation (operating V

as low as 1.5V).

• Standby mode current drain less than or equal to 0.05μA.

Japan : JJY 40/60kHz

Germany : DCF77 77.5kHz
