Datasheet Summary
AN53
The CS5322 Digital Filter by Jerome Johnston Delta-Sigma A/D converters have bee widely accepted by data acquisition designers because of their high performance. One of the highest dynamic range Delta-Sigma converters is the Crystal Semiconductor CS5321/CS5322 chip set. The CS5321 is a fourth order modulator. The CS5322 is a linear phase FIR decimation filter. The purpose of this Technical Brief is to pare the architecture of a general purpose DSP chip with that of the CS5322. General purpose DSPs are available which support either fixed-point arithmetic or floating-point arithmetic. Fixed-point processors
