LA1652V
Overview
The LA1652V receives long-wave standard broadcasts (Japan: JJY, Germany: DCF77, and others), detects the time code
superposed on the long-wave standard waveform, and outputs that information. By using the time code information
received with the LA1652V, applications can automatically correct the clock time.
Functions
RF amplifier, rectifying circuit, detection circuit, time code output, standby circuit.
Features
Low-voltage operation (VCCOP = 1.8V or higher).
Standby mode current less than 0.1A.
Japan: JJY 40/60 kHz
Germany: DCF77 77.5 kHz
