Overview

The LA1650 and LA1650C receive long-wave time standard broadcasts (JG2AS in Japan and DCF77 in Germany) and detect and output the time code multiplexed on the long-wave time standard broadcast signal. Clocks can automatically correct their time using the time code information received by the LA1650 and LA1650C.

Features

• Low-voltage operation (VCC op = 1.2 V and higher)

• Low current drain (500 µA for @ 10 dBµ V input)

• Standby mode current: Less than 1 µA

• High sensitivity (Reception is possible at Vin = 10 dBµ V.)

• Packages: DIP18 (LA1650) Chip (LA1650C)

Functions

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