WebJun 20, 2024 · This will be specified in your controller's datasheet in the DDR4 interface specifications. Note that the driver output impedance may be configurable among various values. 34, 40, and 48 Ohms single-ended impedance are common, and each of these will have a specific corresponding differential pair impedance. WebAnother aspect of RGMII that is different from GMII is that it requires a clock delay skew of 1.5 ns–1.9 ns to either be placed on the board with a delay trace or the delay is created internally in the MAC and/or PHY. The VSC8211 offers this clock delay skew feature on both TX and RX pairs thereby removing the need for a board trace delay.
