New White Paper: Wireless Backhaul Network Node implemented with a Xilinx Zynq SoC

You can use a Xilinx Zynq-7000 SoC to implement a complete wireless backhaul network node, as demonstrated in the reference design found in the new 31-page Xilinx White Paper WP457 “Integrated Single System-on-a-Chip Mobile Backhaul for Small-Cell Deployments.”


One Zynq-7000 device can:


  • Run the application software on the Zynq SoC’s dual-core ARM Cortex-A9 MPCore processor.
  • Implement the backhaul functionality—including timing and synchronization, packet switching, and the wireless modem—using the Zynq SoC’s Programmable Logic (PL).
  • Implement the required interfaces, including 1 GbE and 10 GbE MAC/PCS interfaces, and interfaces to ADCs and DACs using JESD204B or LVDS using the Zynq SoC’s SerDes and programmable I/O ports.


Here’s a block diagram of the design:

And here’s a diagram from the White Paper showing you how the wireless backhaul tasks are distributed to the on-chip ARM Cortex-A9 processor cores and the programmable logic:

The White Paper covers many details including the design of an E-band Modem reference design. Download it here.
