PRODUCTION DATA
The digital filter low-pass filters and decimates the low-resolution, high-speed data from the modulator to produce high-resolution, low-speed output data. The programmable oversampling ratio (OSR) determines the amount of filtering that affects signal bandwidth and conversion noise, and the final data rate through decimation. The output data rate is defined by: fDATA = fMOD / OSR.
The ADC offers the choice of two filter modes: wideband and low latency. The filter mode selection optimizes either the frequency response characteristics (wideband filter mode) or the time domain characteristics (low-latency filter mode).
