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.
