SGMII AC Timing Specifications
This section describes the SGMII transmit and receive AC timing specifications. Transmitter and receiver
characteristics are measured at the transmitter outputs (L1_SD_TXn and L1_SD_TXn) or at the receiver
inputs (L1_SD_RXn and L1_SD_RXn) as depicted in Figure 9 respectively.
