Stratix IV GX and HardCopy IV GX Protocol Support
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 and HardCopy® IV GX ASIC 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.
Figure 1 shows Stratix IV GX FPGA and HardCopy IV GX ASIC key protocol support by typical application.

Stratix IV GX FPGAs and HardCopy IV GX ASICs 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 Quartus® II development tools and SOPC Builder, help to reduce development overhead in both device resources and engineering efforts.
Table 1 shows key protocol data rates and solution packages.
