8.3.4.1
SGMII Transmit AC Timing Specifications
Table 34 provides the SGMII transmit AC timing targets. A source synchronous clock is not provided.
8.3.4.2
SGMII Receive AC Timing Specifications
Table 35 provides the SGMII receive AC timing specifications. Source synchronous clocking is not
supported. Clock is recovered from the data. Figure 17 shows the SGMII receiver input compliance mask
eye diagram.
