The RF Technology Specialist
1 Short Description
The CME8000 is a BiCMOS integrated straight through receiver with build in very high sensitivity
and a pre-decoding of the time signal transmitted from WWVB, DCF77, JJY, MSF and HBG. The
receiver is prepared for multi-mode reception by using an integrated logic. Integrated functions as
stand by mode, integrated antenna switching, integrated crystal switching and a hold mode
function offer features for universal applications.
The power down mode increases the battery lifetime significantly and makes the device ideal for all
kinds of radio controlled time pieces.
2 Features
o Low power consumption (<100µA)
o Very high sensitivity (0.4µV)
o Build in pulse decoding for different protocols
o Switchable for 3 different frequencies
o High selectivity by using crystal filter
o Power down mode
o Only a few external components necessary
o AGC hold mode
o Wide frequency range (40 ... 120 kHz)
o Low power applications (1.2 .. 5.0 V)
o Automatic protocol recognition
o Pre-decoded protocol information
o Fast data transfer to CPU (100ms)
o Use of the CPU clock (32768Hz)
o Improved noise resistance
o Integrated AGC adaptation
Two built-in low impedance antenna switches
(40 Ohm/3V)
o True Bit strength indication
Benefits
o Extended Battery operating time
o Decoding of the signal extremely simplified
o Simplified micro controller software
o Simplified multi frequency handling
o Easy world time piece design
o Automatic country recognition
o True signal quality information
