Description
The Zynq and FMCOMMS2/3/4 Transmitter Configuration block connects your hardware logic to the FMCOMMS2/3/4 radio transmitter hardware. In simulation, this block provides optional ports for center frequency and gain, which the SoC Builder tool maps to hardware pins. The block does not connect to the radio hardware from simulation.
Examples
Packet-Based ADS-B Transceiver
Packet-based systems are common in wireless communications. Data is received over the air and is decoded as discrete packet data on a compute device. For given system requirements, it is difficult to design a system and implement directly on SoC as it often involves long iterations of debugging and integration on hardware since hardware effects are difficult to account for at design time. In this example, you will design packet-based airplane tracking application based on Automatic Dependent Surveillance Broadcast (ADS-B) standard, partitioned between FPGA and embedded processor. Unlike traditional methods, you will simulate the application design with memory interface before implementation on hardware using SoC Blockset™ to shorten development time. You will then validate the design on hardware by automatically generated code from the model.
Transmit and Receive Tones Using AD9361 Dual-Channels
Design, simulate, and deploy dual-channel application system with AD9361 RF card using SoC Blockset™ on Xilinx® Zynq® UltraScale+™ MPSoC ZCU102 Evaluation Kit.
Limitations
In the hardware setup, select one of the supported Xilinx boards. You can find the supported boards in the Libraries list at the top of this page. Set Add-on Card to

Ports
Input
External RF center frequency, specified as a nonnegative finite scalar. The valid center frequency range is from 70 MHz to 6 GHz.
Dependencies
To enable this port, set the Source of center frequency
parameter to Input Port.
Data Types: double
External gain, specified as a numeric scalar or a 1-by-2 numeric vector. The valid gain range is –10 dB to 77 dB. The resolution is 0.25 dB.
Set the gain based on the Channel mapping parameter configuration.
For a single channel, specify the gain as a scalar.
For two channels that use the same gain value, specify the gain as a scalar. The block applies the gain by scalar expansion.
For two channels that use different gain values, specify the gain as a 1-by-2 vector. The
ith element of the vector is applied to theith channel specified by the Channel mapping parameter.
Dependencies
To enable this port, set the Source of gain parameter to
Input Port.

Parameters
The Zynq and FMCOMMS2/3/4 Transmitter Configuration block supports up to two channels to send data. Use the Channel mapping parameter to indicate whether to use a single channel or dual channels. For each channel, you can set the Gain (dB) parameter independently, or you can apply the same setting to all channels. If you select direct digital synthesis (DDS) transmission for the Data source select parameter, you can also set all DDS-based parameters independently. All other parameter values are applied to each channel in use.
