SWITCHING CHARACTERISTICS

(Inputs: Logic 0 = 0 V, Logic 1 = VL; CL = 20 pF)

SWITCHING CHARACTERISTICS - SERIAL AUDIO PORTS

(Inputs: Logic 0 = 0 V, Logic 1 = VL; CL = 20 pF)

Notes: 5. The active edge of ISCLK is programmable in Software mode.

6. The polarity of ILRCK is programmable in Software mode.

7. Prevents the previous ISCLK edge from being interpreted as the first one after ILRCK has changed.

8. This setup time ensures that this ISCLK edge is interpreted as the first one after ILRCK has changed.
