The RGMII specification requires that the signal clock be delayed by 1/2 bit time (2 ns) at the receiving end of the data path. Recommended PCB Routing Guidelines for S34MLxx SLC NAND Flash Memory During the length mismatch analysis, the PCB designer must pay attention to signal polarities (rising and falling edge triggers) as well as lead/lag timing to determine whether a specific Control signal should always lead or lag compared to another signal or data bus. Try to use via as less as possible on RGMII interface traces to minimize the timing skew. MX8 QXP Hardware Developer’s Guide, Rev. • Use dedicated ground and power planes. Table 3. 3 Stackup. These guidelines cover parts placement, various critical traces routing like RF, Host interfaces routing like SDIO/SPI, USB, UART, power routing, and GND pour. Altium Designer ® includes layout tools and an advanced layer stack manager, giving you full control over all aspects of your design. Note: The VSC8224 device supports all three of the above methods. 15mm min track/clearance, up to 0. It provides recommendations on the implementation of multipurpose media-independent interfaces MII/ RMII, RGMII and SGMII, including multiple implementations of these interfaces. The VSC8224 contains an internal delay element connected to each TX_CLK and RX_CLK pin, which can provide the necessary clock delays for the RGMII interface without the need for PCB trace This section focuses on topics that need to be considered when designing a PCB containing NXP Ethernet devices.
