【应用笔记】AN477:使用FPGA和HardCopy ASIC设计RGMII接口(AN 477: Designing RGMII Interfaces with FPGAs and HardCopy ASICs)
本应用笔记描述了如何使用Stratix®, Arria®, and Cyclone® FPGAs和HardCopy® ASICs设计一个简化的吉比特媒体独立接口(Reduced Gigabit Media Independent Interface,RGMII)。RGMII是一个对IEEE802.3z GMII减少引脚数目的可替代的方案。通过既使用时钟上升沿又使用时钟下降沿的时钟数据和复用控制信号来实现引脚数目的减少。
This application note describes how to design a reduced gigabit media independent interface
(RGMII) with Stratix®, Arria®, and Cyclone® FPGAs and HardCopy® ASICs.
RGMII is an alternative to the IEEE 802.3z GMII with reduced pin count. Pin count reduction
is achieved by clocking data on both the rising and falling edges of the clock and by
multiplexing the control signals.AN477.pdf
