INTERFACING TO DIGITAL AUDIO
RECEIVERS AND TRANSMITTERS
The SRC4194 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 transmitters to address
these applications.
Figure 13 illustrates interfacing the DIR1703 to the
SRC4194 input port. The DIR1703 operates from a single
+3.3V supply, which requires that the V
IO
supply (pin 56)
for the SRC4194 to be set to +3.3V for interface
compatibility.

Once again, the V

Like the SRC4194 output ports, the DIT4096 and DIT4192
audio serial ports may be configured as a Master or Slave.
In cases where the SRC4194 output port is set to Master
mode and the DIT4096/4192 is configured as the Slave, it
is recommended to use the reference clock source for the
corresponding section of the SRC4194 as the master
clock source for the DIT4096/4192. This will ensure that
the transmitter audio serial port clocks, SYNC and SCLK,
are synchronized to the master clock source.
