MPC8313E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2.1

Freescale Semiconductor

Ethernet: Three-Speed Ethernet, MII Management

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.

Notes:

1. Measured at receiver.

2. Each UI is 800 ps ± 100 ppm.

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

4. Refer to the

RapidIO™ 1x/4x LP Serial Physical Layer Specification, for interpretation of jitter specifications.
