Input Arguments
rfDataConverter
— RF data converter
soc.RFDataConverter
object
RF data converter, specified as an soc.RFDataConverter
object. Via Ethernet, this object connects the host computer to the RF data converter on
the connected SoC device. Use the object functions and properties of this object to
configure the RF data converter.
tileId
— Identifier of RF-DAC tile
0
| 1
| 2
| 3
Identifier of the RF-DAC tile connected to the programmable logic, specified as
0
, 1
, 2
, or
3
. Available options for the RF-DAC tile ID vary according to the
specified RFSoC device. A tile contains several DACs, accessible as channels, and
several shared timing units, including a clock and PLL.
Data Types: single
| double
| int8
| int16
| int32
| int64
| uint8
| uint16
| uint32
| uint64
channelId
— Channel identifier
0
| 1
| 2
| 3
Channel identifier for the selected DAC tile, specified as 0
,
1
, 2
, or 3
. Available
options for the channel ID vary according to the specified RFSoC device.
Data Types: single

| int32
| int64
| uint8
| uint16
| uint32
| uint64
mixerType
— Type of mixer
"Bypassed"
| "Coarse"
| "Fine"
Type of mixer used in the RF-DAC digital path, specified as
"Bypassed"
, "Coarse"
, or
"Fine"
. When you specify "Bypassed"
, no mixer is
included in the DAC digital path. "Coarse"
specifies the coarse
mixer, which enables mixing the data with a carrier at frequency ratios set by input
mixerFrequency
. "Fine"
specifies the fine
mixer, which enables the data to be shifted up or down in frequency by the
fineMixerScale
input value.
Data Types: char
| string
mixerFrequency
— Frequency for coarse or fine mixer
"Fs/2"
| "Fs/4"
| "-Fs/4"
| scalar
When you specify "Coarse"
as the mixerType
,
the mixer frequency must be specified as one of these values:
"Fs/2"
- Half of the sampling frequency"Fs/4"
- Quarter of the sampling frequency
When you specify "Fine"
as the mixerType
,
the mixer frequency must be a scalar. Units of the mixer frequency are in MHz.
Data Types: char
| string
| double
eventSource
— Source of update event for RF-DAC mixer
"Immediate"
| "Slice"
| "Tile"
| "SysRef"
| "Marker"
| "PL"
Source of the update event for the RF-DAC mixer, specified as
"Immediate"
, "Slice"
, "Tile"
,
"SysRef"
, "Marker"
, or "PL"
.
An event update can be made intermediately or can wait for another event within the
system. For detailed information on the event sources, see "Dynamic Update Events"
section in Zynq UltraScale+ RFSoC RF Data Converter v2.3.
Data Types: char
| string
NCOPhase
— Phase value for output of NCO mixer
positive scalar value
Phase value for the output of the numerically-controlled oscillator (NCO) mixer,
specified as a positive scalar. The NCO phase applies only when you specify a fine mixer
by setting input mixerType
to "Fine"
.
Data Types: double
fineMixerScale
— Scale for fine mixer
"Auto"
| "1"
| "0.7"
Scale for fine mixer, specified as "Auto"
,
"1"
, or "0.7"
. To specify a fine mixer, set input
mixerType
to "Fine"
.
Data Types: char
| string
