16/33

The Clock Output Select register selects the frequency of the clock output pin relative to the PLL clock output.

The PLL clock runs at 2048fs for 32, 44.1, and 48kHz, at 1024fs for 88.2kHz and 96 kHz, and at 512fs for

176.4kHz and 192kHz.

3.3.3 Post-Scale Link

For multi-channel applications, the post-scale values can be linked to the value of channel 1 for ease of use and

update the values faster.

3.3.4 Biquad Coefficient Link

For ease of use, all channels can use the biquad coefficients loaded into the Channel 1 Coefficient RAM space

by setting the BQL bit to 1. Then any EQ updates would only have to be performed once.

3.4 Configuration Register E (address 04h)

The scale and mix functionality can be used to mix adjacent channels instead of for bass management. By set-

ting this bit(BME must be set to 0) odd channels will be mixed with their adjacent even channel and output in

the place of the even channel. The odd channel wills pass-through unscaled. The values used for this function

are the same as for bass management. Since this function occurs post channel mapping a large number of

possibilities are present for two channel mixing. Up to four mixed channels can be obtained.

When VOLEN set to 1, volume operation is normal. When set to 0, volume operation is bypassed and the vol-

ume stages are all set to pass-through. This also eliminates the digital volume offset of ~-0.6dB that is used to
