The VPX-D16A4-SRIO is a rugged high performance DSP/FPGA card in the compact VITA 65, 3U OpenVPX form factor. It is ideal for applications such as EW, SW radio, imaging or radar in harsh field deployment environments.

The card features 4x ARM A15 cores, 16x C66x+ DSP cores and various accelerators across two TI Keystone SoCs, each with its own large DDR3 memory bank and a 20Gbaud SRIO link to the VPX backplane. They are closely coupled with the Hyper-Link bus. The main DSP is connected via PCI Express and AIF2 CPRI interfaces to a Xilinx Kintex-7 K325T FPGA, which has its own backplane MGT, LDVS, GPIO and seri-al ports and a flexible clock generation PLL, enabling specialised I/O such as multi-channel RF or high speed ADC/DAC interfaces. All devices are also connected with Gigabit Ethernet.

A full Linux BSP and example software support is provided to accelerate customer development, based on TI’s Linux and Multicore Software Development Kit and the Xilinx Vivado FPGA development suite. In addition, CommAgility’s field proven LTE PHY software is available integrated with the card, with various options for L2/L3 software stacks.
