A Power Line Communication (PLC) device that is resilient to cross-band interference. The PLC device is configured to communicate on AC power wiring in the frequency range of 9 kilohertz to 500 kilohertz and does not use automatic gain control prior to analog-to-digital conversion. The PLC device includes an over-sampled analog-to-digital converter with a sample clock of at least 10 megahertz and includes a loop filter that maintains a noise power spectral density that does not exceed three decibels above a minimum noise floor, of the noise power spectral density, at 80 kilohertz or above, and a digital filter and decimator configured to remove quantization noise, where a decimation factor of the decimator is such that it provides an output decimation rate between 350 kilohertz and 1.6 megahertz. |
