116. K WORDSELECT and DATA WORD SELECT Word select WS indicates whether the data sample is from the left or the right audio channel It has the same frequency as the sample rate of the digital audio signal This can be 32 44 1 or 48kHz Normal polarity is low for a left sample and high for a right sample So within the low state of the WS line the data bits for the left channel are transferred and within the high state the data bits of the right channel are transferred CLOCK The CLOCK signal CLK indicates when DataTips must be set and when DataTips must be read The frequency depends on the speed of the I2S bus but is always a factor of the frequency of the WS signal It can be 48x 64x 96 128x In our case it is 48x the sample rate frequency 2 1168MHz The WS LEFT SAMPLE signal is in phase with the WS signal Transition of the WS always happens on a falling edge of the CLK DATA DATA contains all data bits Data bits are set by the transmitting device and read by the receiving device The position of the DATA bits within the WS signal is very important There are several formats for this In our case we always use Philips 125 format no Japanese or Sony format The number of data bits per channel depends on the used devices Timing of the I2S bus in case of Philips 125 is shown in the next figure f f RIGHT SAMPLE CL96532086_061 eps 080999 Figure 8 32 GB64 EM CDR775 Faultfinding Guide Measurements
