SGMII AC Timing Specifications

Note:

Specifications are valid at the recommended operating conditions listed in Table 3.

Transmitter and receiver AC characteristics are measured at the transmitter outputs (SR[1–2]_TX[n] and SR[1–2]_TX[n]) or at

the receiver inputs (SR[1–2]_RX[n] and SR[1–2]_RX[n]) as depicted in Figure 19, respectively.

Table 29 provides the SGMII transmit AC timing specifications. A source synchronous clock is not supported. The AC timing

specifications do not include REF_CLK jitter.

Table 30 provides the SGMII receiver AC timing specifications. The AC timing specifications do not include REF_CLK jitter.
