PRODUCTION DATA
For applications where low latency with minimal phase deviation (within the audio band) is critical, the low-latency decimation filters on the PCM182x can be used. The device supports these filters with a group delay of approximately seven samples with an almost linear phase response within the 0.365 × fS frequency band. This section provides the filter performance specifications and various plots for all supported output sampling rates for the low-latency filters.
