SGMII, MII, RGMII, RMII, and RTBI AC Timing Specifications

The AC timing specifications for SGMII, MII, RGMII, RMII and RTBI are presented in this section.

8.3.1

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.
