Typical Application of PL460
The PL460 modem is designed to be managed by an external host microcontroller through a 4-line
standard Serial Peripheral Interface (SPI).
Four additional signals allow the host to control the PL460: STBY, ENABLE, TXEN and NRST. Another
signal EXTIN from the PL460 is used to signal events from the PL460 to the host controller.
The thermal monitoring functionality checks the internal temperature of the device and allows the
PL460 to adapt its operation in case of overheating. The functionality is enabled using the THEN
input. Two output signals are used to generate different temperature warnings, NTHW0 and THW1.
The first warning, NTHW0, can be managed by the host controller and the second warning, THW1, is
managed directly by the PL460 using the G1 input.
The following figure illustrates a typical example of the PL460 modem:

The zero-crossing detection (VZC) is an optional feature and its usage depends on the PLC protocol
specification.
Refer to the Microchip reference designs for a detailed description of the usage of the
aforementioned control signals and features.
