INTERFACING TO DIGITAL AUDIO RECEIVERS
AND TRANSMITTERS
The SRC4192 and SRC4193 input and output ports are
designed to interface to a variety of audio devices, including
receivers and transmitters commonly used for AES/EBU,
S/PDIF, and CP1201 communications.
Texas Instruments manufactures the DIR1703 digital audio
interface receiver and DIT4096/4192 digital audio transmit-
ters to address these applications.
Figure 12 illustrates interfacing the DIR1703 to the SRC4192
or SRC4193 input port. The DIR1703 operates from a single
+3.3V supply, which requires the V
IO
supply (pin 7) for the
SRC4192 or SRC4193 to be set to +3.3V for interface
compatibility.
