PRODUCTION DATA
The device supports a fully programmable mixer feature that can mix the various input channels with the custom programmable scale factor to generate the final output channels. The 8x4 Mixer is for the 8 Main ASI inputs and 4 outputs. The 2x4 Mixer is for the 2 AUX ASI inputs and 4 outputs. The 4 outputs are RDAC, RDAC2, LDAC and LDAC2.
Tables below shows the coefficients for the programmable 8x4 Mixer and the programmable 2x4 Mixer.
| Register Name | DAC Register co-efficient Mapping | Reset Value |
|---|---|---|
| ASI_CH1_RDAC_MIX(15:0) | B0_P17(R8-R9) | 0x0000 |
| ASI_CH1_LDAC_MIX(15:0) | B0_P17(R10-R11) | 0x4000 |
| ASI_CH1_RDAC2_MIX(15:0) | B0_P17(R12-R13) | 0x0000 |
| ASI_CH1_LDAC2_MIX(15:0) | B0_P17(R14-R15) | 0x0000 |
| Register Name | DAC Register co-efficient Mapping | Reset Value |
|---|---|---|
| ASI_AUX_CH1_RDAC_MIX(15:0) | B0_P17(R72-R73) | 0x0000 |
| ASI_AUX_CH1_LDAC_MIX(15:0) | B0_P17(R74-R75) | 0x4000 |
| ASI_AUX_CH1_RDAC2_MIX(15:0) | B0_P17(R76-R77) | 0x0000 |
| ASI_AUX_CH1_LDAC2_MIX(15:0) | B0_P17(R78-R79) | 0x4000 |
Similarly the programmable mixer setting for input channel can be done using the ASI_AUX_CH2_(RDAC/LDAC/RDAC2/LDAC2) and ASI_AUX_CH2_(RDAC/LDAC/RDAC2/LDAC2) register bits.
TI recommends using the PPC3 GUI for configuring the programmable coefficients settings; for more details see the Using the TAx5x1x Programmable Digital Channel Mixer application report and the PurePathâ„¢ console graphical development suite.
