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, 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
CMMC-8P-MF module which is programmed with a pre-defined serial interface protocol.
