Pins 12 and 13, Inputs
Function:
The master clock frequency must be either 32x, 48x, 64x or 96x the input sample rate. Table 8 illustrates
the standard audio sample rates and the required master clock frequencies.
Clocks the individual serial data bits into the DIL and DIR pins. Refer to Figure 33
The word clock determines which channel is currently being input on the serial audio data input, SDATA.
The frequency of the word clock must be at 8x the baseband sample rate. Refer to Figure 33.
Two’s complement MSB-first serial data is input on these pins. The data is clocked into DIL and DIR via
the bit clock. Refer to Figure 33.
