Analog Front-End 5.1 PLC coupling circuitry description Atmel PLC coupling reference designs have been designed to achieve high performance, low cost and simplicity. With these values on mind, Atmel has developed a set of PLC couplings covering frequencies up to 472 kHz compliant with different applicable regulations. Atmel PLC technology is purely digital and does not require external DAC/ADC, thus simplifying the external required circuitry. Generally Atmel PLC coupling reference designs make use of few passive components plus a Class D amplification stage for transmission. All PLC coupling reference designs are generally composed by the same sub-circuits: Transmission Stage Reception Stage Filtering Stage Coupling Stage Figure 5-1. PLC coupling block diagram A particular reference design can contain more than one sub-circuit of the same kind (i.e.: two transmission stages). 5.1.1 Transmission Stage The transmission stage adapts the EMIT signals and amplifies them if required. It can be composed by: Driver: A group of resistors which adapt the EMIT signals to either control the Class-D amplifier or to be filtered by the next stage. Amplifier: If required, a Class-D amplifier which generates a square waveform from 0 to VDD is included. Bias and protection: A couple of resistors and a couple of Schottky barrier diodes provide a DC component and provide protection from received disturbances. Transmission stage shall be always followed by a filtering stage.
