4.6.4 Assumptions and Dependencies

The Smart Meter DSP module is specifically designed to accept samples from an Energy Metering AFE - Δ/Σ ADC using an OSR = 64, at an input sample rate of 16.000 kHz. This input data stream is further filtered to an internal sample rate of 4.000 kHz for generation of metrology quantities. All computed metrology quantities are available at a rate of approximately 1 Hz when using default settings.
