DDS/Mixer Configuration Parameters - 2024.1 English

For the DDS/Mixer library element, use the following list of configurable parameters and default values:

Table 66 DDS/Mixer Configuration Parameters

Name	Type	Default	Description
DATA_TYPE	typename	cint16	Data Type.
WINDOW_VSIZE	unsigned	256	Input/Output window size.
MIXER_MODE	unsigned	2	The mode of operation of the dds_mixer. 0: dds only 1: dds plus single data channel mixer 2: dds plus two data channel mixer, for symmetrical carrier
P_API	unsigned	0	0: window, 1: stream
UUT_SSR	unsigned	1	Super Sample Rate SSR parameter. Defaults to 1.
NITER	unsigned	16	See Common Configuration Parameters
DIFF_TOLERANCE	unsigned	0	See Common Configuration Parameters
INITIAL_DDS_OFFSET	unsigned	0	Initial DDS offset.
DDS_PHASE_INC	unsigned	0xD6555555	DDS Phase Increment.
DATA_STIM_TYPE	unsigned	0	See STIM_TYPE in Common Configuration Parameters
ROUND_MODE	unsigned	0	See Common Configuration Parameters
SAT_MODE	unsigned	1	See Common Configuration Parameters
USE_PHASE_RELOAD	unsigned	static phase	0: ‘static phase’ 1: ‘reload phase offset’

Additionally, for the DDS/Mixer library element that uses LUTs, an additional template parameter is available:

Name	Type	Default	Description
SFDR	unsigned	90	specifies the expected Spurious Free Dynamic Range that the useR expects from the generated design.
