APPLICATION INFORMATION
GENERAL DESCRIPTION
The AFE031 is an integrated powerline communication analog front-end (AFE) device built from a variety of
functional blocks that work in conjunction with a microcontroller. The AFE031 provides the interface between the
microcontroller and a line coupling circuit. The AFE031 delivers high performance and is designed to work with a
minimum number of external components. Consisting of a variety of functional and configurable blocks, the
AFE031 simplifies design efforts and reduces the time to market of many applications.
The AFE031 includes three primary functional blocks:
Power Amplifier (PA)
Transmitter (Tx)
Receiver (Rx)
The AFE031 also consists of other support circuitry blocks that provide zero crossing detection, an additional
two-wire communications channel, and power-saving biasing blocks (see the Functional Block Diagram). All of
these functional blocks are digitally controlled by the microcontroller through the serial interface (SPI).
Figure 24 shows a typical powerline communications application system diagram. Table 1 is a complete list of
the sections within the AFE031.
