| 4 | | 17 | To ensure the correct operation in the desired Nyquist zone, one needs to configure the application's correct operating zone. Software Control All the capabilities provided by the RFSoC RF-ADC and RF-DAC tiles are highly configurable, with most parameters being configurable at run time using software control. To ensure the development team doesn't have to write everything from scratch, Xilinx provides a software application programming interface (API) for both bare- metal development and PetaLinux developments. Thanks to the Xilinx LibMetal layer, the same API is used in bare metal and PetaLinux operating systems. The API is split into several different segments: 1. Xrfdc–This API contains the main user interface 2. Xrdfc_mts–This API contains all the multi-tile synchronization functions 3. Xrdfc_mixer–This API contains all the mixer control and configuration functions 4. Xrdfc_Clock–This API contains all the clock controls and configuration functions 5. Xrdfc_MB–This API contains all the multi-band control and configuration functions 6. Xrdfc_hw–This contains the hardware register map and masks 7. Xrdfc_Intr–This provides the interrupt handling for the RF Data Converter These APIs enable software developers to control and configure the RF Data Converter at run time. Xilinx Zynq ® UltraScale+ MPSoCs Multiprocessors Learn more > Modern communications and wireless technologies require higher performance and tighter integration. The RFSoC enables system developers to address these challenges using monolithic 16nm FinFET CMOS technology because of digital calibration and equalization techniques. This allows the complex RF-ADC and RF-DAC to work across Nyquist zones, sampling signals at Giga Samples Per Second rates. Hard macro implementations of up and down converters, numerically controlled oscillators, and mixers are integrated with the RF-ADC and RF-DAC. The architecture of the RFSoC has been designed so that it is capable of synchronization between multiple tiles or even devices. This ability to synchronize is important for beamforming applications as deployed in 5G communications and RADAR. It is also essential to control the RF data converters using software APIs that provide all of the necessary software functions to help us work with the RF Data Converter, its clocks, and even multi-tile synchronization. Combined with the processing system and programmable logic available within the RFSoC, these unique capabilities ensure its ability to meet modern communication and RADAR systems' demands.
