VSC8584 Evaluation Board 2 Introduction The VSC8584 device is a low-power, quad-port Gigabit Ethernet transceiver with four SerDes interfaces for quad-port dual media capability. It also includes an integrated quad port I2C multiplexer (MUX) to control SFPs or PoE modules. The VSC8584 supports IEEE 802.
VSC8584 Evaluation Board 3 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.
VSC8584 Evaluation Board 3.1.5 3.1.6 3.1.7 External 1588 Clock Option The user may choose to provide an external 1588 REFCLK via SMA connections to J65 and J66. Zero ohm jumpers may need to be removed and or installed to connect via these clock inputs. The board is built with connections for external 1588 REFCLK, unless otherwise indicated in documentation accompanying the specific board delivered.
VSC8584 Evaluation Board Figure 4 • 1588 Daisy-Chain SPI Traffic Pattern (PHY port 3 egress) 3.1.8 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. Note: The factory programmed Rabbit board IP address is 10.9.70.
VSC8584 Evaluation Board 4 Quick Start This section shows the quick start for the VSC8584. 4.1 Connecting the Power Supply 4.2 PC Software Installation The evaluation board uses 5 VDC to power the on-board regulators creating the 3.3 V, 2.5 V, and 1.0 V rails which drive the devices as well as modules. The evaluation board can be powered up using the power pack which provides the 5 VDC. Simply plug the AC adaptor into a wall socket and the barrel end into J67 (see the upper right corner of Figure 1).
VSC8584 Evaluation Board 4.4 Using the Control Software 4.4.1 CAT5 to SGMII with Clause 37 AutoNeg Enabled Connect the VSC8584EV Rabbit microcontroller RJ-45 directly to the PC or through a network switch if properly configured. Apply 5 VDC to the EVB. Launch the GUI by double-clicking the GUI shortcut located in C:\ViperGUI_4_67 or on the desktop if it has been moved there. The GUI connection window shown in the following figure should appear.
VSC8584 Evaluation Board Figure 6 • MII Registers GUI Window Be sure the device is up and running by reading MII Register 0. It should read back 0 × 1040. Reading back all 0’s or all 1’s indicates a problem. A checked box means the bit is set to “1,” if unchecked it is “0.” 4.4.2 Board Initialization and Running PGY Scripts Once the evaluation board connectivity has been established and confirmed, the PHY should be initialized.

VSC8584 Evaluation Board Steps for SGMI forwarding port 0 ↔ port 1: 1. Set up the Copper traffic source (i.e., IXIA or Smartbits) 2. Connect an Ethernet cable to an RJ-45 Port 0. 3. Connect two matched coax cables as follows: J1 to J6 J2 to J7 to J10 to J9 4. Write using the "Micro Page Registers" window: 18'd 0 × 80F0. 5. When “Micro Page” 18’d is read back, bit 15 will clear. 6. Linkup bit is in MII Reg 1, bit 2 (MII 1.
