RGMII布线指导 RGMII Layout Guide 2015-11-30 2017-06-19 lics 网络设备一定离不开MAC和PHY,有MAC和PHY的地方就有相应的接口,无论看得见或者看不见,它就在那里,不悲不喜。. 3 Clock TimingSignal Board Layout Considerations 58 3. The KD-RD10x2-POFSW Gigabit-POF Switch Reference Design provides guidelines for design and evaluation capabilities in a flexible platform, enabling product designers to successfully shorten the time-to-market for KD1012-based end products. Introduction. The reference manual for the board specified a set of pin numbers for the 4 Ethernet PHYs on the board, which is shown in the image attached. 3版本要求:通过PCB走线使得时钟相对数据线延迟1. With higher clock rates and pico seconds edge rate devices, PCB interconnects act. We worked on a Wireless Chipset project in which Vu was DV engineer for one of the "matured" digital IP where Vu demonstrated a very high level of DV skills. Each channel has its own clock, data, and control signals. We are using Linux for this design. 2 with 50MHz reference clock input/output option - Media Independent Interface (MII) in PHY/MAC mode Advanced Switch Capabilities - IEEE 802. 3az Energy Efficient Ethernet (EEE) IEEE 802. ) to the PCB edge in order to minimize fringe effect and lower EMI emissions. PCB Layout: Ethernet Traces are these four just here ^^^^ I've read through this website on tips regarding Ethernet traces. Step 2: Modify the Example Design to HUB board hardware.
