IT900 will provide nearly 20 times greater throughput than the IT800 series using Yitran's highly robust DCSK modulation technology.
LONDON -- Endesa, Spain's largest utility and one of EuropeeIUs five leading electricity companies, Renesas Technology the worldwide leading supplier of semiconductor solutions to the metering industry, and Yitran a leading PLC fabless semiconductor company and the inventor of the IT800 DCSK based powerline modulation technique, have signed an agreement on 27th July 2006 to jointly develop an open specification for Automatic Meter Management (AMM).
The physical layer is based on YitraneIUs IT800 using DCSK modulation technique that has been especially designed to cope with the characteristic distortion phenomena of distribution powerlines.
Renesas originally selected YitraneIUs DCSK technology due to its robust communications capability and signed a license agreement with Yitran in 2002 to incorporate YitraneIUs DCSK technology into its M16C family of microcontrollers to provide single chip PLC solutions.
