S/PDIF INPUT AND OUTPUT  

The EVAL-ADAU1467Z evaluation board has two optical S/PDIF 
interfaces. One interface is an input that converts the optical 
signal to an electrical signal, which is sent to the 

ADAU1467

 

S/PDIF receiver (the SPDIFIN pin). The other interface is an 
optical output that takes the electrical output from th

ADAU1467

 

S/PDIF transmitter (the SPDIFOUT pin) and converts it to an 
optical signal. Figure 57 shows the locations of the optical input 
connector and the optical output connector.  
 

S/PDIF Optical Transmitter and Receiver 

The 

ADAU1467

 S/PDIF interfaces are connected directly to 

optical transmitter and receiver connectors, which convert the 
electrical signals to and from optical signals, respectively. The 
connectors accept standard TOSLINK connectors and optical 
fiber cables (see Figure 58).
