Power line transceiver using ST7538
General description
The EVALST7538DUAL board integrates the
ST7538 power line transceiver along with the
power supply section, the signal coupling
interface section, crystal oscillator and device
protections. The coupling interface section has
been realized for communication on CENELEC
Band A used mainly for AMR applications, with
the possibility of programmable switching
between 72kHz and 86kHz communication
channels. This half-duplex “dual channel”
communication feature has been implemented
through optimized receiving and transmitting
filters on the board.
EVALST7538DUAL board must be connected to a
PC through the EVALCOMMBOARD general
purpose board. The dedicated SW running on the
PC can be downloaded from
