WM8595
DIGITAL ROUTING CONTROL
w
The WM8595 includes a highly flexible digital routing multiplexer, allowing independent systems to be
directly connected to the WM8595 without the need for glue logic. The WM8595 consists of two
digital audio ‘ports’, each with four pins, which can be configured to connect to any of the three
internal WM8595 systems (ADC, DAC1 or DAC2) or to any other digital audio ports. An additional
ADC data pin and two GPIO pins are available as auxiliary bidirectional data pins. A simplified block
diagram of the digital routing is shown in Figure 21:

The default configuration of the clocking is as shown in Figure 22 below. It is expected that this
configuration will satisfy the majority of the use cases for the WM8595, but if it doesn’t it is possible
to route the signals differently. See the following pages for details of this setup.
