Figure 61. Digital Mixer

The LM49352 includes two separate and independent DSP blocks, one for the DAC and the other for the ADC.

The digital mixer also allows both DSP blocks to be cascaded together in either order so that the DSP effects

from both blocks can be combined into the same signal path. For example, the 5 band parametric EQ of each

DSP block can be combined together to form a 10 band parametric EQ for added flexibility.

This register is used to control the LM49352's digital mixer:
