Ordering number : ENN6310A
30300RM (OT) No. 6310-1/14
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 A for @ 10 dB V input)
Standby mode current: Less than 1 A
High sensitivity (Reception is possible at
Vin = 10 dB V.)
Packages: DIP18 (LA1650)
Chip (LA1650C)
Functions
RF amplifier, rectifier, detector, time code output,
standby circuit
