MAX9880A Evaluation Kit
paths is accessed by selecting either of its Filtering
blocks and filtering for the DAI2 signal path is enabled/
disabled by clicking its associated Filtering block.
The DAI1 Filtering blocks open the DAI1 Filtering win-
dow. The Filtering Mode radio buttons configure the
filtering mode for DAI1’s DAC and ADC signals. When
the Voice Filters (IIR) radio button is selected, group
boxes for the ADC Digital Audio Filter ( ADC Highpass
Filter ) and DAC Digital Audio Filter ( DAC Highpass
Filter ) registers are visible, providing a selection of five
highpass filter types. When the Audio Filters (FIR) radio
button is selected, a DC-blocking filter is available. The
ADC and DAC DC-blocking filters are enabled/disabled
by selecting/deselecting the appropriate checkbox. The
DC-blocking filter for the DAI2 path is enabled/disabled
by clicking on the DAI2 Filtering block.
The DAI1 and DAI2 Filtering blocks are also used to
display the current state of their digital filters (see Figure
11). The filter blocks display an image, representing the
type of filtering (highpass or DC blocking) being applied
to the DAI_ signals. In addition, the DAI1 Filtering blocks
display the configured filtering mode (voice filters or
music filters).
SPDM Output Registers
The SPDM Configuration and Input registers are
accessed through the SPDM CLOCK , SPDML , and
SPDMR blocks on the Digital Audio tab (see Figure 12).
These blocks are used to enable/disable the SPDM data
outputs and configure the SPDM clock rate (SPDMCLK).
The SPDM input mixers (MIXSPDML, MIXSPDMR) are
configured by selecting the MIX block associated with
the SPDMDATA output.
To utilize the SPDM data output, configure the EV kit
hardware as described in the SPDM Output section.
Digital Gain Registers
The digital gain registers are accessed by selecting the
appropriate gain blocks on the Digital Audio tab (see
Table 10). The Voice DAC Level register is divided into
two gain blocks. The first gain block is for DAC gain and
the second is for DAC muting and level control. The gain
block coming from the ADC Filtering block opens the
ADC Level Control window, providing access to both
the ADC gain and level-control settings.
