Figure 6. Typical Connection Diagram, No External Master Clock

* When no external master clock is supplied to the part, both input and output must be set to salve mode

for the part to operate properly. This is done by connecting the MS_SEL pin to ground through a resis-

tance of 0

Ω to 1 kΩ ± 1% as stated in Table 1, “Serial Audio Port Master/Slave and Clock Ratio Select

Startup Options (MS_SEL),” on page 13

** The connection (VL or GND) and value of these two resistors determines the mode of operation for the

input and output serial ports as described in Table 1, “Serial Audio Port Master/Slave and Clock Ratio

Select Startup Options (MS_SEL)", Table 2, “Serial Audio Input Port Startup Options (SAIF)", and

Table 3, “Serial Audio Output Port Startup Options (SAOF)", all on page 13.
