19.6 GbE Transmit and Receive Topology
19.6.1 GbE Transmit Topology
19.6.1.1 GbE Transmit Clock Topology
Figure 138 shows the routing topology of the GbE Transmit clock. The transmit clock
topology is for the routing of GbEn_TxCLK (RGMII) or GbEn_CLK (RMII). The routing
guidelines for the Transmit Data and Transmit Control signals in section
Section 19.6.1.2 are referenced to the to the Transmit clock. Table 83 provides routing
guidelines for the Transmit Clock signals.
