Cyclone® IV FPGAs


Cyclone® IV FPGAs continue the Intel® Cyclone® series tradition of offering low power and high functionality. Cyclone® IV GX FPGAs feature integrated transceivers at up to 3.125 Gbps.

The logic and routing core fabric is surrounded by I/O elements (IOEs) and phase-locked loops (PLLs). Both GX and E devices have four general-purpose PLLs located at each corner of the die. The Cyclone® IV GX FPGA has I/O elements at the top, bottom, and right sides of the die, while the Cyclone® IV E FPGA has I/Os on all four sides of the die. The left side of the Cyclone® IV GX FPGA die has up to eight transceivers in two quads consisting of four transceivers per quad. The top and bottom of each transceiver quad features a multi-purpose PLL (MPLL) that the transceiver or the FPGA fabric can use.

Integrated Transceivers

Cyclone® IV GX FPGAs are built with Intel's proven GX transceiver technology, known for excellent jitter performance and superior signal integrity. The PCI-SIG-compliant transceiver variant supports a wide variety of serial protocols. Cyclone® IV GX FPGAs also feature hard intellectual property (IP) block for PCI Express x1, x2, and x4 in rootport and endpoint configurations.
