... The device operates in one of three operational modes. The allowed sample rate range in each mode is auto-detected. The CS4352 will auto-detect the correct mode when the input sample rate (Fs), defined by the LRCK fre- quency, falls within one of the ranges illustrated in each mode are not supported. ...

... VA_H, VA, VD, and VL connected to clean supplies. If the ground planes are split between digital ground and analog ground, the GND pins of the CS4352 should be connected to the analog ground plane. All signals, especially clocks, should be kept away from the VBIAS and VQ pins in order to avoid unwanted coupling into the DAC ...

... Popguard Transient Control The CS4352 uses a novel technique to minimize the effects of output transients during power-up and power- down. This technology, when used with external DC-blocking capacitors in series with the audio outputs, minimizes the audio transients commonly produced by single-ended, single-supply converters activat- ed inside the DAC when the RST pin is toggled and requires no other external control, aside from choosing the appropriate DC-blocking capacitors ...
