Serial Giga Media Independent Interface (SGMII)
The serial gigabit media-independent interface (SGMII) is a variant of MII used for Gigabit Ethernet but can also carry 10/100 Mbit/s Ethernet. It uses differential pairs at 625 MHz clock frequency DDR for TX and RX data and TX and RX clocks. It differs from GMII by its low-power and low pin-count 8b/10b-coded SerDes. Transmit and receive path each use one differential pair for data and another differential pair for clock. The TX/RX clocks must be generated on device output but are optional on device input (clock recovery may be used alternatively). 10/100 Mbit/s Ethernet is carried by duplicating data words 100/10 times each, so the clock is always at 625 MHz.
• Simultaneously display PCS or GMII protocol packet data in tabular form, including command parsing.
• “Data Filter” & “Idle Filter” filter unwanted data and idle to save memory.
• “Search” searches specific data.
• SGMII PCS & GMII statistics include numbers of packets, individual command, different data length, and errors
• Support 10Mbps/100Mbps/1000Mbps
• SGMII command trigger
a. Trigger parameters include commands and data in order to cover all kinds of packets.
b. GMII & PCS Packet
c. Trigger CRC Error, Frame Error, Propagation Error, Start of Packet, End of Packet, Carrier Extend, Configuration.
d. The Trigger-Out port is to trigger a DSO to capture waveforms

Advanced usage of the report area
a. Dual report correlation: PCS and GMII reports are related to each other.
Double-click to track the corresponding data in another report area.
ex: Click the PCS area report to link to the GMII corresponding report.
b. Statistics list: Quickly categorize and track the location of data iwth statistical functions.
