CMMR-8D
RC Module
1. CME8000 Description
The CME8000 is a BICMOS integrated straight through receiver with in-built 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-modus reception by using an integrated logic.
Integrated functions such as stand-by mode, integrated antenna switching, integrated crystal
switching and a hold function offer features for universal applications.
2. CMMR-8D Description
Together with the ferrite antenna, the CMMR-8D module forms a complete receiver unit for
single, dual or triple frequency radio control signal reception. Depending on the application or

evaluation that this module is applied on, the part number for ordering differs. (For detail see
part-numbering and ordering section).
This module has pin outs for all available pins on the receiver IC CME8000. Via easy
interface with a separate MCU, the module can readily receive, recognize and decode to
digital form the selected long wave signal received via the antenna. Output of the decoded
stream of digital data is available on the DATA pin of the module and can be fed into the
MCU for translation into time information necessary for the intended application.
