Description
The RTX16 integrates sixteen (eight IQ), digitizing channels and sixteen (eight IQ) waveform generation channels with real-time signal processing on a SOM IO module for demanding, real-time DSP applications. The tight coupling of the analog I/O within the Ultrascale+ RFSoC FPGA core provides low latency, optimized for architectures such as beam-steering, SDR, RADAR, and LIDAR front end sensor digitizing and processing. The Quad Mesh system interface sustains transfer rates at 16 Gbps to four peers concurrently facilitating creation of large meshes within high performance real-time systems.
The onboard 1760-pin Xilinx ZU49DR with 8 GB external DDR4 RAM addressable as two 64-bit banks, provides a very high performance DSP core. On-chip integration of multichannel, GSPS analog IO, zero-wait SRAM block memory and quad ARM CPU cores enable real-time signal processing at extremely high rates.
The RTX16 can be fully customized using VHDL using the supplied board support package (BSP). The BSP provides standard IP cores for arbitrary waveform playback, and contiguous capture of ADC data of specified length (framed mode) DDR4 memory control and QuadMesh communications.

Power Dissipation
Power dissipation is heavily dependent on the firmware implementation. Using more SERDES channels, more ARM cores and enabling RFdc core will increase power consumption.
Software Tools
Software development tools for the module provide comprehensive support via C++ libraries, including device drivers, data buffering, card controls, and utilities that allow developers to be productive from the outset. The target ARM processors run a 64-bit variant of Petalinux, source for which is supplied within the BSP.
