Virtex-7-Based AMC Targets Wireless Front Ends

Long-term-evolution (LTE) wireless front-end systems that require multiple 10G CPRI links at up to rate option 8 can opt for the Xilinx Virtex-7 FPGA-based AMC-V7 interface and processing card in the Advanced Mezzanine Card (AMC) form factor. Developed by CommAgility, the card features an IDT CPS-1848 Serial RapidIO (SRIO) Gen 2 switch that supports SRI) V2.1 at up to 20 Gbits/s per port. Also included are three front-panel SFP+ optical interfaces that provide flexible high-speed links; they’re configurable as CPRI, OBSAI, Gigabit Ethernet, SRIO, or other standards. An optional SRIO mini-SAS connector delivers high-speed cabled connectivity. Front-panel or backplane clock I/O achieve timing and synchronization (GPS is an option as well). The Virtex-7 FPGA comes as a VX415T-2 device as the standard build, with options up to the VX690T-2 available for very-high-performance applications. Memory includes two banks of DDR3 SDRAM and a bank of flash memory for storing FPGA configurations and additional software. Separate glue control enables control, FPGA configuration, and flash reprogramming over SRIO.
