... CME8000 receiver IC 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, JJY40, JJY60, MSF and HBG. The receiver is prepared for multi-frequency and country reception by using an integrated logic. The CME8000 is connected to an in-built micro-controller in the CME-BUS module which is programmed with a pre-defined serial interface protocol ...
