FIGURE 11. Typical Circuit Configuration, Hardware Mode.
The line driver outputs may be connected to cable or fiber
optic transmission media in the target application. Figures 12
and 13 show typical connections for driving either balanced
twisted-pair or unbalanced coaxial cable. Either of these
connections will support rates up to 96kHz.
Figure 14 illustrates the connection to an optical transmitter
module, used primarily in consumer applications, such as
CD or DVD players. The optical transmitter data rate is
limited to 6Mb/s, so it will not support 96kHz data rates. The
optical interface is typically reserved for lower rate transmis-
sion, such as 44.1kHz or 48kHz.
DUAL-WIRE OPERATION USING MONO MODE
In order to support stereo 96kHz transmission for legacy
systems, which utilize AES-3 receivers that operate up to a
maximum of 48kHz, it is necessary to use two DIT4096
transmitters in what is referred to as a Dual-Wire configura-
tion. Each transmitter carries data for only one channel in
this configuration.
