3. The external AC coupling capacitor is required. It is recommended that it be placed near the device transmitter outputs.

4. For recommended operating conditions, see Table 3.

3.19.9.3.2 SGMII AC measurement details

Transmitter and receiver AC characteristics are measured at the transmitter outputs

( SDn_TXn_P and SDn_TXn_N) or at the receiver inputs ( SDn_RXn_P and

SDn_RXn_N) respectively, as depicted in this figure.

3.19.9.3.3 SGMII and SGMII 2.5x receiver AC timing specification

This table provides the SGMII and SGMII 2.5x receiver AC timing specifications. The

AC timing specifications do not include RefClk jitter. Source synchronous clocking is not

supported. Clock is recovered from the data.
