Altera provides a range of complete PCI-SIG-compliant FPGA solutions for a variety of x1, x4, and x8 PCI Express applications. The solutions include configurable PCI Express intellectual property (IP) cores and development boards for endpoint, bridge, switch, and root complex functionality. The solutions enable simple and fast protocol implementation, thereby reducing design risk, shortening development times, and allowing you to concentrate on the core functions of the system design.
The PCI Express hard IP that implements PHY-MAC, data link, and transaction layer functionality is also available in Stratix® IV GX FPGAs, Arria® II FPGAs, Cyclone® IV GX FPGAs, and HardCopy® IV GX ASICs.
Integrated PCI Express Solutions
Utilizing built-in transceivers to implement the protocol in a single device, Stratix II GX, Stratix IV GX, Arria V, Arria II, Arria GX, and Cyclone IV GX (1) FPGAs provide a fully integrated PCI Express-compliant solution for multi-lane (x1, x4, and x8), high-performance applications. Table 1 provides an overview of the complete PCI Express solution for Altera® devices.

- Cyclone IV GX FPGAs support PCI Express-compliant solution for multi-lane (x1, x2, and x4) applications.
External Transceiver PCI Express Solutions
For PCI Express applications, you can use an external transceiver (PHY device) with an FPGA. For applications that require low power, you can use Cyclone series FPGAs with an external transceiver; for applications requiring the highest density and performance, you can use Stratix series FPGAs and HardCopy ASICs.
Table 2 shows the Altera FPGAs and ASICs with external PHY solutions for PCI Express.
