    Abstract: A transmitting device may control digital-to-analog converter (DAC) illumination to optimize signal to noise ratio of a transmission signal. DAC illumination may be adjusted based, at least in part, on analog gain and estimated total transmit power of a particular transmission signal. For each destination, total transmit power may be estimated based on tone map, amplitude map, back-off settings, or other characteristics. The estimated total transmit power is used to determine an appropriate analog gain. Once analog gain and total transmit power are known, fine control of SNR may be achieved by adjusting power level in the digital domain. A digital power control setting is used to scale the amplitude of the digital baseband signal prior to DAC operation. The DAC illumination of the digital baseband signal allows the DAC to operate at an optimized power level within the digital range of the DAC.

    Abstract: A powerline communication (PLC) power supply and modem interface can be implemented using a power supply processing unit coupled with a PLC modem unit. The power supply processing unit generates a composite PLC signal comprising a PLC signal and a DC power signal modulated with a zero cross signal (all determined from an AC powerline signal). High-powered components of the PLC modem unit can cause signal distortion in the zero cross signal component of the composite PLC signal making it difficult to extract zero cross information. An error correction unit can be implemented at the PLC modem unit to minimize the signal distortion and generate a zero cross signal with little or no error. The PLC modem unit also extracts the PLC signal and the DC power signal from the composite PLC signal, and processes the PLC signal using the zero cross information extracted from the corrected zero cross signal.

Also, the transformer coupling unit can receive a plurality of communication signals on each of a plurality of powerline communication channels. The transformer coupling unit can combine the plurality of the communication signals into a communication signal. The transformer coupling unit may then couple the communication signal to an analog front end and other processing units for processing the communication signal.

    Abstract: A powerline communication (PLC) device can be configured to execute functionality for zero cross sampling and detection. When the PLC device is directly coupled to a high-voltage PLC network, the PLC device can comprise printed safety capacitors in series with a high-voltage input AC powerline signal to safely couple the high-voltage AC powerline signal to the low-voltage processing circuit. The PLC device can also comprise an ADC to sample a scaled AC powerline signal and to obtain zero cross information. When the PLC device is part of an embedded PLC application, dynamic loading can affect the integrity of a low voltage zero cross signal that is used to extract zero cross information. After digitizing the zero cross signal, the PLC device can execute functionality to minimize/eliminate voltage drops caused by dynamic loading and obtain the zero cross information.
