CS5342-CZZ Summary of contents
Page 1
... The CS5342 uses a 5th-order, multi-bit Delta-Sigma modulator followed by digital filtering and decimation, which removes the need for an external anti-alias filter. The CS5342 is available in a 16-pin TSSOP package in Commercial grade (-10° to 70° C). The CDB5342 Cus- tomer Demonstration board is also available for device evaluation and implementation suggestions ...

... APPLICATIONS 4.1 Single-, Double-, and Quad-Speed Modes The CS5342 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, 96x only available in Master Mode ...

... Fs. Additionally, Quad-Speed Slave Mode is only specified for operation with a VA and ±5%. A unique feature of the CS5342 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 CS5342 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 according to the frequency of the MCLK. Table 3 shows a listing of the external MCLK/LRCK ratios that are required. ...
Page 17
... Synchronization of Multiple Devices In systems where multiple ADCs are required, care must be taken to achieve simultaneous sampling. To ensure synchronous sampling, the MCLK and LRCK must be the same for all of the CS5342’s in the system. 4.8 Capacitor Size on the Reference Pin (FILT+) The CS5342 requires an external capacitance on the internal reference voltage pin, FILT+. The size of this decoupling capacitor affects the low frequency distortion performance, as shown in capacitor values used to optimize low frequency distortion performance ...
