configureDACTile

Configure the PLL and sampling rate of DAC tile

Syntax

configureDACTile(rfDataConverter,tileId,PLLSrc,PLLRefClk,samplingRate)

Description

configureDACTile(rfDataConverter,tileId,PLLSrc,PLLRefClk,samplingRate) configures the source and reference clock of the phase-locked loop (PLL) and sampling rate of the specified DAC tile.

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

PLLSrc — Source clock signal of the PLL

"Internal" | "External LMK/LMX"

Source clock signal of the PLL in the RF-DAC tile, specified as "Internal" or "External LMK/LMX". The source clock signal can come from either the clock in the tile or the external source.

Data Types: char | string

PLLRefClk — Frequency of reference clock to PLL

positive scalar

Frequency of the reference clock to the PLL, specified as a positive scalar. This reference clock frequency drives the PLL in the RF-DAC tile.

Data Types: double

samplingRate — Sampling rate

positive scalar

Sampling rate in MHz, specified as a positive scalar.

Data Types: double
