Overview

The LA1652C 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 LA1652C. Note that the LA1652C is a bare chip product that is not packaged.

Features

• Low-voltage operation (operating VCC as low as 1.8V).

• Standby mode current drain less than or equal to 0.1µA.

Japan : JJY 40/60kHz

Germany : DCF77 77.5kHz

Functions

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