ST7538Q FSK power line transceiver description
11/56
signal is fed into the differential power amplifier to get four times the voltage swing and a
current capability up to 370 mA rms.
When in reception mode (i.e. RxTx line at high level), an incoming signal at the RAI line is
demodulated and converted to a digital bit stream on the RxD pin.
The internal control register, which contains the operating parameters of the ST7538Q
transceiver, can be programmed only using the SPI interface. The control register settings
include the header recognition and frame length count functions, which can be used to apply
byte and frame synchronization to the received messages.
