Page 4: Introduction
1588v2 timing implementation. The VSC8584 device offers a seamless integration between IEEE 1588v2 and the MACsec engine with no loss of precision. The VSC8584 also supports a ring resiliency feature that allows a 1000BASE-T connected PHY port to switch between master and slave timing without having to interrupt the 1000BASE-T link. -

VSC8584 Evaluation Board General Description The evaluation board in Figure 1 provides the user a way to evaluate the VSC8584 device in multiple configurations. Four RJ-45 connectors are provided for copper media interfaces. The four SFP cages allow for evaluation of the fiber media interconnects. The MAC interface is provided via SMA connectors. -

3.1.7 1588 Daisy-Chain SPI Time-Stamping Connection The VSC8584 device enables daisy-chaining multiple devices to reduce the number of pins required to transmit time stamping information to system ASICs gathering IEEE 1588 time stamps. For users with two or more 8584EV boards, the following single-ended connections shown below are required from the master device to slave device: J75 pin 6 to J77 pin 6 (1588_SPI_CLK output →... -
Page 7: Network Interface Microcontroller Card
A “Rabbit” microcontroller card is included to facilitate a software interface to the registers on the VSC8584. The controller card has a hard coded static IP address. Refer to the label on the card for the value. This address is required by the user to initiate communications via the board and the GUI. -
Page 8: Quick Start
Please record and inform Microsemi of the new IP address of the board when you return so that Microsemi can connect to and reconfigure the board. Re-label the Rabbit board with the new IP. -

"Connect." The display next to the IP address window should change to "Connected." If it does not, check the IP address, or your network configuration until connection with the EVB can be successfully established. Double-click on “MII Registers” and the window shown in Figure 6 should appear: VPPD-03500 VSC8584 User Guide Revision 1.0... -

The script syntax is command, phy address (in decimal), register address (in decimal), and register content (in either hexadecimal or decimal). VPPD-03500 VSC8584 User Guide Revision 1.0... -
Page 11: Copper Media Operation (1000Base-T)
A single register write and some external coax cables enables 1G Ethernet traffic to be received by the VSC8584 RJ-45 port, routed through the VSC8584 and externally via coax loopback cables through the SGMII interface and transmitted back to the traffic source on the same copper port. First configure the SerDes in SGMII mode by writing to Micro page 18’d. -
