... APPLICATIONS 4.1 Single-, Double-, and Quad-Speed Modes The CS5341 can support output sample rates from 2 kHz to 200 kHz. The proper speed mode can be de- termined by the desired output sample rate and the external MCLK/LRCK ratio, as shown in Speed Mode Single-Speed Mode Double-Speed Mode Quad-Speed Mode * Quad-Speed Mode, 64x only available in Master Mode ...

... Fs to maximize system performance. A unique feature of the CS5341 is the automatic selection of either Single-, Double- or Quad-Speed Mode when operating as a clock slave. The auto-mode select feature negates the need to configure the Mode pins to correspond to the desired mode ...

... Master Clock The CS5341 requires a Master clock (MCLK) which runs the internal sampling circuits and digital filters. There is also an internal MCLK divider which is automatically activated based on the speed mode and frequency of the MCLK. Table 4 lists some common audio output sample rates and the required MCLK frequency. Please note that not all of the listed sample rates are supported when operating with a fast MCLK (512x, 256x, 128x for Single-, Double-, and Quad-Speed Modes, respectively) ...

... LRCK signals are the same for all of the CS5341’s in the system. If only one master clock source is needed, one solution is to place one CS5341 in Master Mode, and slave all of the other CS5341’s to the one master. If multiple master clock sources are needed, a possible solution would be to supply all clocks from the same external source and time the CS5341 reset with the inactive (falling) edge of MCLK ...

... Capacitor Size on the Reference Pin (FILT+) The CS5341 requires an external capacitance on the internal reference voltage pin, FILT+. The size of this decoupling capacitor will affect the low frequency distortion performance as shown in capacitor values used to optimize low frequency distortion performance. This plot was taken using the CDB5341 evaluation platform, with the device running in Single-Speed Mode and VA=VD=VL=5 V ...
