Overview
Stratix IV GX was the top of Intel's 40 nm line and remains heavily deployed in wireline, defence and medical equipment. The EP4SGX230 offers 228,000 logic elements, 1,288 embedded multipliers, 17,133 Kb of TriMatrix memory and thirty-six transceiver channels running to 8.5 Gb/s.
Because those transceiver channels and the hard PCIe Gen2 x8 block are integrated, the device can host multi-lane backplane links, CPRI/JESD204B radio interfaces and a host PCIe connection without discrete PHYs — which is why Stratix IV GX boards are still kept in service and re-sourced long after the family's introduction.
Key Benefits
36 × 8.5 Gb/s transceiver lanes plus hard PCIe Gen2 x8 for multi-lane backplanes and radio interfaces. 1,288 hardware multipliers for real DSP throughput. TriMatrix memory architecture (M9K / M144K / MLAB) provides flexible buffering for packet and video datapaths.
Applications
Wireline and wireless infrastructure, military radar and electronic warfare, medical imaging, professional broadcast, semiconductor test equipment, and long-lifecycle industrial signal processing platforms.
