10 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

10.1 Application Information

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 ). All of these functional blocks are

digitally controlled by the microcontroller through the serial interface (SPI).

Figure 47 shows a typical powerline communications application system diagram. Table 19 is a complete list of

the sections within the AFE031.
