Actel公司最近推出的SX系列FPGA产品,时钟输出能达到4ns,最高时钟频率为320MHz,从而使该系列产品完全适合在从Ethernet(以太网)到66MHz PCI设计的广阔领域中应用。 SX系列FPGA采用0.35μm、三层金属工艺,金属—金属反熔丝阻抗低达25Ω。在结构上与以往FPGA不同之处在于逻辑块的设计和器件结构。SX系列逻辑块设计基础为门海结构,即逻辑块像网格一样在整个硅面上交
Actel’s recently introduced SX family of FPGAs delivers clock speeds up to 4ns and clock speeds up to 320MHz, making the family well-suited for use in a wide range of applications from Ethernet (Ethernet) to 66MHz PCI designs. SX series FPGA 0.35μm, three metal technology, metal-metal anti-fuse impedance as low as 25Ω. The difference in structure from the previous FPGAs lies in the logic block design and device structure. SX series of logic blocks based on the design of the door sea structure, that is, logic blocks like the grid in the entire silicon surface to pay
