8. Multiple AC’97 & Multi-Channel
DS-1S allows connection with up to two AC’97s, and plays back up to 4-channel PCM data.
Therefore, the
following applications can be realized.
8-1. AC’97 Digital Docking
AC’97 digital docking can be realized by mounting the secondary AC’97 on the docking station side.
Typical example of digital docking connection between DS-1S and AC’97s is represented in the circuit
diagram below.

Isolation Buffer
When digital docking interface is made with the main side (PC side) powered on, but docking station side
powered off, it may be not desirable for the secondary AC’97 that each output signal from the AC-Link is
applied to the secondary AC’97 that remains in powered off state.
In order to avoid such a situation, it is
necessary to place an additional isolation buffer on the PC side (or docking station side).
8-2. 4-Channel Speaker System
4-channel speaker system can be realized by the connection of DS-1S with two 2-channel AC’97s as
described at “8-1. AC’97 Digital Docking” or using the AC’97 that includes 4-channel D/A converters.
Then, 4-channel PCM data can be played back at one time.
