Stratix IV GX Protocol Support

Figure 1. Key Protocols and Applications


Transceiver-based devices are now commonly used to meet the ever increasing data bandwidth requirements of communications, networking, storage, broadcast, and imaging applications. A number of industry standard protocols are emerging to support these applications.

The Stratix® IV GX FPGA transceiver architecture greatly simplifies protocol implementation by adding dedicated functionality within the physical coding sublayer (PCS) block of the transceiver to achieve compliance. The transceiver has been specifically designed to support the widest possible range of protocol standards across multiple data rates, while offering excellent signal integrity and keeping power consumption low.

Stratix IV GX FPGAs support a complete solution for protocol-based applications. The solution includes dedicated intellectual property (IP) cores, development boards, reference designs, collateral, and protocol-specific characterization reports. The solutions, combined with Intel® Quartus® Prime development tools and Platform Designer (formerly Qsys), help to reduce development overhead in both device resources and engineering efforts.
