Typical PCM output performance is measured and characterized with an Audio Precision SYS-2722 192kHz test system and a

PCM4222EVM evaluation module modified for use with the PCM4220. Measurement bandwidth and weighting settings are noted in the

Parameter and Conditions columns. THD+N is measured without the use of weighting filters. Master mode operation is utilized for all

typical performance parameters, with the master clock input frequency (MCKI) set to 12.288MHz.
