... The CS4334 family of devices supports two modes of operation. The devices operate in Base Rate Mode (BRM) when MCLK/LRCK is 256, 384 or 512 and in High Rate Mode (HRM) when MCLK/LRCK is 128 or 192. High Rate Mode allows input sample rates up to 100 kHz ...
Page 13
... SYSTEM DESIGN The CS4334 family accepts data at standard audio sample rates including 48, 44.1 and 32 kHz in BRM and 96, 88.2 and 64 kHz in HRM. Audio data is input via the serial data input pin (SDATA). The Left/Right Clock (LRCK) defines the channel and delineation of data, and the Serial Clock (SCLK) clocks audio data into the input data buffer. The CS4334/5/8/9 differ in serial data formats as shown in 4 ...

... Q 4.5 Output Transient Control The CS4334 family uses Popguard® technology to minimize the effects of output transients during power- up and power-down. This technique eliminates the audio transients commonly produced by single-ended single-supply converters when it is implemented with external DC-blocking capacitors connected in series with the audio outputs. To make best use of this feature necessary to understand its operation. ...
