Cool Phoenix 2 - Flexible PLC Modem Solution


Cool Phoenix 2 (CPX2) being the second generation device of the award winning Cool Phoenix family, has kept its flexible concept allowing a single design supporting multiple standards.
Whilst the device is pin compatible to its predecessor it offers more memory as well as higher performance supporting multiple frequency bands like CENELEC, FCC and ARIB. The AES security engine features ECB, CBC and CCM modes with key lengths of 128, 192 and 256 bit respectively.


  • Software configurable PLC modem supporting multiple PLC standards (G3, PRIME)
  • Fully certified protocol stacks with well documented API provided
  • Multiple frequency bands supported (CENELEC A, FCC, ARIB)
  • Superior dynamic range
  • Excellent power consumption figures
  • Competitive Bill of Material



Block Diagram

Cool Phoenix 2 integrates a MAC controller as well as a high performance digital signal processor (DSP) for physical layer (PHY) implementation. The embedded analogue front end includes an adaptive gain amplifier with automatic gain control (AGC) functions. This ensures exceptional signal quality in highly dynamic and harsh network environments as found in metering applications. As a result the solution shows outstanding robustness and unique sensitivity characteristics.

・In combination with the wide range of Renesas pin, software compatible and scalable microcontrollers for metering applications, the Cool Phoenix 2 powerline modem solution provides a perfect fit for smart electricity meter platforms. Cool Phoenix 2 is also ideal for other Smart Grid applications such as street lighting.
