Introduction www.ti.com




2 IntroductionThe DP83826 is a low latency, deterministic, and low power Ethernet Physical Layer transceiver withintegrated PMD sublayers to support both 10BASE-Te and 100BASE-TX Ethernet protocols. TheDP83826 interfaces directly to twisted pair media via an external transformer and offers integrated cablediagnostic tools, built-in self-test and loopback capabilities for ease of use. It interfaces to the MAC layerthrough a Media Independent Interface (MII) or a Reduced MII (RMII) both in Master and Slave mode. The50 MHz clock in RMII Master mode is synchronized to the MDI derived clock to improve the system's jitter.The DP83826EVM will demonstrate all features of DP83826. The EVM supports 10BASE-Te and100BASE-TX Ethernet protocols. The EVM includes connections to use the DP83826 MII and RMII pinsthrough header pins.

2.2 Operation – Quick Setup

2.2.1 Power SupplyThe DP83826EVM power is supplied by the 5-12V input connection in Figure 3. Single supply operationuses on-board LDOs to generate the voltages required for operating various sections of the EVM. Powercan also be supplied externally to individual voltage rails. The micro-USB supplies power to the on-boardLDOs that power all microcontroller related components.

NOTE: Before supplying power at the 5-12V input, ensure the correct shunts are added to theappropriate headers to properly operate the on-board LDOs as seen in Figure 4.

Figure 3. DP83826EVM Power Headers

Figure 4. DP83826EVM Power Inputs

In the case the user would like to power the EVM from external sources, J7, J8, and J9, VDDA, VDDIOand the fiber optic transceivers respectively, can be removed and supplied power at pin 2 for all threejumpers. J23 can also be used to supply an external 5V to the USB and MSP430.

http://www.ti.com






2.2.2 SoftwareThe on-board MSP430 comes pre-programmed and ready to use. When using this EVM for the first timeon a Windows 7 (or above) PC, MSP430 drivers and USB-2-MDIO software utility will have to be installed.USB-2-MDIO software can be used for accessing the PHY's registers. In the case where an externalMSP430 or EZFET is needed, the user may simply connect the TST and RST pins of their device to theDP83826EVM.

Figure 5. DP83826EVM External MSP Connection

2.2.2.1 MSP430 DriverInstall the latest MSP430 drive from this website: http://software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/MSP430_FET_Drivers/latest/index_FDS.html .

2.2.2.2 USB-2-MDIO SoftwareDownload the software from http://www.ti.com/tool/usb-2-mdio .

The webpage also contains the User’s Guide for installing and using the software. Because the MSP430is on-board the DP83826EVM, it is not necessary to purchase a separate MSP430 Launchpad kit andconnect to the PHY using wires.

In the case the on-board MSP430 cannot be used for some reason, MDIO and MDC pins are also brokenout on J1 and J2 pins, respectively. Users can connect an MSP430 launchpad or their own MDIO-MDCutility on J1 and J2 to access the PHY.

Table 2. DP83826EVM Applications

N0. TEST CASES APPLICATIONS HOW TO USE

1 MII/RMII to Copper

Run traffic between MII/RMII and Copper. Connect to DP83826 EVM or MAC Systemusing Header pins.

Perform IEEE and UNH compliance testing Using onboard MSP430 and software.

Run EMI/EMC Test on EVM Use internal PRBS and loopback. OnboardMSP430 can be used for register access.

Measure Power Dissipation Connect external power supplies.

External MAC loopback Connect external MAC to headers and useMAC loopback register settings

50MHz output clock Optional Clock out SMA

2 Loopback Data received by the PHY can be looped backthrough the interface without needing a MAC. Use onboard MSP430 to enable loopback.

3 Repeater Mode RMII back to back as range extender. Two EVMs can be connected back to backusing custom header cable.

4 Low Power modesDemonstrate EEE Use onboard MSP430 to enable EEE.

Demonstrate Sleep and Power down mode Use onboard MSP430 to activate lowpower mode

4 Configurations Options

4.1 MDIO Register AccessTo update or read the registers of the device, the user can simply connect the DP83826EVM to acomputer and use the USB-2-MDIO software. The EVM is designed to easily enable and test strapfunctionality through software instead without the need to modify the board and hardware. This allows forsimple hardware and software support for those that do not have MDIO communication capability. Theregister map used for the DP83826EVM can be found in section 8.7 of the DP83826E Datasheet.

More information on how to access the DP83826 MDIO status and control registers can be found in theUSB-2-MDIO Software User's Guide .
