DSP Modes with Single Output Signal Input Steams LT (Interpolati on) NCO_EN DUC_FORMAT DAC_SRC0 value MXMODE0/ 1 Description 1 1 0 Real 0x1 NRZ, RTZ, RF, DES2x Single channel mode (no up-conversion). 1 1 0 Real 0x1 DES1x Single channel mode with dual-edge samples w/o interpolation (DES1X). The JESD204C interface provides all samples (no interpolation). 2, 4, 6 or 8 2-256x 1 Real 0x1, 0x3, 0x7, 0xF NRZ, RTZ, RF, DES2x 1-4 DUC channels with single real output DAC_SRC0 settings are for 1, 2, 3, or 4 DUC channels respectively. These modes only produce one output signal, so only one DAC is required. The table shows the programming to use DACA (MXMODE1 should be set to disabled). The user may elect to use DACB instead by programming DAC_SRC1 and MXMODE1 (and setting MXMODE0 to disabled). The user may also program DAC_SRC1=DAC_SRC0 and MXMODE1=MXMODE0 and then tie the DAC outputs together to get more output power. Table 7-6. DSP Modes with Dual Output Signal Input Steams LT (Interpola tion) NCO_EN DUC_FO RMAT DAC_SRC0 value DAC_SRC1 value MXMODE 0/1 Description 2 1 0 N/A 0x1 0x2 NRZ, RTZ, RF, DES2x Dual channel mode (no up-conversion) 2, 4, 6 or 8 2-256x 1 Real any bits set any bits set NRZ, RTZ, RF, DES2x 1-4 DUC channels with two real outputs 2 2-256x 1 or 0 Complex 0x1 0x4 NRZ, RTZ, RF, DES2x 1 DUC channel with complex output: DACA outputs real samples DACB outputs imaginary samples 4 2-256x 1 or 0 Complex 0x3 0xC NRZ, RTZ, RF, DES2x 2 DUC channels with complex output These modes produce two output signals (and uses both DACs). The user may elect to swap the values programmed into DAC_SRC0 and DAC_SRC1 to swap the output signals. Typically MXMODE0 and MXMODE1 are set to the same setting, however this is not required.
