LA1654FN Datasheet, PDF (1/4 Pages) Sanyo Semicon Device – Time Code Reception IC

Ordering number : ENA0204
LA1654FN
Monolithic Linear IC
Time Code Reception IC
Overview
The LA1654FN 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 LA1654 FN.
Functions
• RF amplifier, rectifier, detector, time code output, and standby circuit.
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
