... The CS5340 achieves higher analog performance and supports a wider range of output sample rates, including 192 kHz. This additional per- formance is the main reason for the increased power consumption of the CS5340 relative to the CS5333. Parameter ...

... The CS5333 and CS5340 are both available in a 16-pin TSSOP package. As can be seen from Table 2, all but three pins correlate directly in terms of functionality. These three pins account for a difference in operational mode selection and a separate voltage supply pin for the CS5340 digital core. ...

... Typical Connection Diagrams Figures 1 and 2 illustrate the typical connection diagram for the CS5333 and CS5340 respectively. The analog and digital core of the CS5333 are powered from VA, which can be set from 1 3.3 V. The VL supply pin powers the digital interface logic from 1 3.3 V and can be set independently from VA. ...

... Both the analog and digital cores can operate independently from 3 5.0 V. The VL pin of the CS5340 supplies the digital interface logic, supports a wide operating range from 1 5.0 V, and can be powered independently from the VA and VD power supplies. ...

... CS5333. The CS5333 supports an MCLK/LRCK ratio of 256x, 384x, 512x, and 768x in Base Rate mode and 128x, 192x, 256x and 384x in High Rate mode. The CS5340 cannot support ratios of 192x, 384x, or 768x. See Table 4. Due to the auto-speed mode detect circuitry implemented in the CS5340, not all sam- ple rate ranges are supported in Slave mode ...

... A passive input filter can be used with the CS5340, however, the full analog performance of the CS5340 will not be realized. Figure 5 illustrates a unity gain, passive input filter solution and the resulting distortion performance. Please note that in this case the dynamic range performance of the CS5340 will not be lim- ited by the input filter; only the distortion performance is affected. ...

... Some applications may require signal attenuation prior to the converter. The full-scale input voltage of the CS5340 will scale with the analog power supply voltage. For VA = 5.0 V, the full-scale input voltage is approximately 2.8 Vpp Vrms. Typical consumer audio line level outputs range from 1 Vrms. ...

... The size of the decoupling capacitor on this reference pin will affect the low frequency distortion performance. The recommended solution for the CS5333 the FILT+ pin and analog ground. The recommended solution for the CS5340 is to use a 0.1 µ in parallel with capacitor for cost sensitive applications ...
