CS4350
Time-Division Multiplex (TDM) Mode
Four TDM interface modes are available that allow the CS4350 to input stereo PCM data in one of 4 time
“slots”. Figure 14 shows the serial port connections necessary to input 8-channel TDM data into four
CS4350 devices, and the corresponding DIF[2:0] pin or register-bit settings required for each CS4350.
Figure 15 shows the TDM data format for each of the four CS4350 devices shown in Figure 14.
