CS8420

13.5.1

Pin Description - Hardware Mode 4

Overall Device Control:

DFC0, DFC1 - Data Flow Control Inputs

DFC0 and DFC1 inputs determine the major data flow options available in Hardware mode, according to Table 5.

Audio Input Interface:

SDIN - Serial Audio Input Port Data Input

Audio data serial input pin. This data will be transmitted out the AES3 port.

ISCLK - Serial Audio Input Port Bit Clock Input or Output

Serial bit clock for audio data on the SDIN pin.

ILRCK - Serial Audio Input Port Left/Right Clock Input or Output

Word rate clock for the audio data on the SDIN pin. The frequency will be at the input sample rate (Fsi)

APMS - Serial Audio Input Port Master or Slave

APMS should be connected to VD+ to set serial audio input port as a master, or connected to DGND to set the port

as a slave.

Audio Output Interface:

SDOUT - Serial Audio Output Port Data Output

Audio data serial output pin. This is also a start-up option pin, and requires a pull-up or pull-down resistor.
