... APPLICATIONS 3.1 Operational Mode/Sample Rate Range Select The output sample rate, Fs, can be adjusted from 2 kHz to 216 kHz. The CS5381 must be set to the proper speed mode via the mode pins, M1 and M0. Refer to M1 (Pin 14) M0 (Pin 13 3.2 System Clocking The device supports operation in either Master Mode, where the left/right and serial clocks are synchronous- ly generated on-chip, or Slave Mode, which requires external generation of the left/right and serial clocks ...
Page 16
... Table 2. CS5381 Common Master Clock Frequencies 3.2.2 Slave Mode LRCK and SCLK operate as inputs in Slave mode recommended that the left/right clock be synchro- nously derived from the master clock and must be equal to Fs also recommended that the serial clock be synchronously derived from the master clock and be equal to 64x Fs to maximize system performance ...

... High-Pass Filter and DC Offset Calibration The operational amplifiers in the input circuitry driving the CS5381 may generate a small DC offset into the A/D converter. The CS5381 includes a high-pass filter after the decimator to remove any DC offset which could result in recording a DC level, possibly yielding “clicks” when switching between devices in a multi- channel system ...
Page 18
... MCLK and LRCK must be the same for all of the CS5381’s in the system. If only one master clock source is needed, one solution is to place one CS5381 in Master mode, and slave all of the other CS5381’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 CS5381 reset with the falling edge of MCLK ...

... Capacitor Size on the Reference Pin (FILT+) The CS5381 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. The THD+N curves in were measured with VA=VD=VL Single-Speed Master Mode with a full-scale sinewave input ...
