WM8599

Product Preview

PP Rev 1.0 January 2007

There are a total of ten (five stereo) analogue input channels and four (two stereo) DAC output

channels. Two of the ten input channels can be routed to the ADC. Six of the 14 total channels can

be routed to the analogue outputs.

Figure 15 illustrates the various blocks of the analogue routing paths within the WM8599. The

following sections describe the control bits associated with the WM8599 analogue paths. Figure 15

also shows where these control bits take affect on the WM8599.

ANALOGUE VOLUME CONTROL

Each analogue bypass channel includes analogue volume control. Volume changes can be applied

to each channel immediately as they are written. Alternatively, all volume changes can be written,

and then all volume changes can be applied simultaneously using the volume update feature.

Volume control includes optional zero cross functionality. When zero cross is enabled, volume

changes are not applied until the output level crosses the DC level of the analogue channel (VMID).

Zero cross helps to prevent pop and click noise when changing volume settings.
