ST7540 FSK powerline transceiver evaluation board
  • active Active

The EVALST7540-2 board integrates the ST7540 power line transceiver along with the power supply section, the signal coupling interface section, the crystal oscillator and device protections. The coupling interface section has been realized for communication around 72 kHz carrier frequency, within the european CENELEC standard A-band specified for automatic meter reading (AMR) applications. This communication feature has been optimized through tuned receiving and transmitting filters on the board. The EVALST7540-2 board must be connected to a PC through the EVALCOMMBOARD general purpose board. The dedicated graphical user interface (GUI) running on the PC can be downloaded from “” web page.

The typical application environment consists of two or more EVALST7540-2 connected to the same mains line, each connected to its own EVALCOMMBOARD controlled by a PC running the EVALCOMMBOARD GUI software.
