Please upgrade to a Xilinx. If you’re not getting a link, I’d first check that the 88E is getting a clock and all required voltages, then check that the jumpers are set for the correct physical layer I’m guessing twisted-pair copper? Alaska Gigabit Ethernet Designed to meet the demands of next generation green networks. It has negative logic reset. I made several measurements to the clock and voltages of this chip actually 2 chips since this board has two ethernet ports – same problem with both of them , and it seems that there is no problem.

Do I have to set up the mode MII manually, i. Hello everyone, many thanks for the replies. I understand that on configuration “B”the jumper J39 does not has any physical scope 2V5 to 2V5but we’ve seen same default factory connections on HTG board.
If etherhet not getting a link, I’d first check that the 88E is getting a clock and all required voltages, then check that the jumpers are set for the correct physical layer I’m guessing twisted-pair copper? I spend several weeks in trying found if something happens with the clock the problem with ML board above.
Marvell 88E PHY Configuration Steps – Altera Wiki
The 88E encodes 3 bits on each config input using 8 possible connections: Can anyone help me understand what does the following Tables means. Sorry for the delay, I was out of the office last week.
Apart from the jumbers for Ethernft mode, I cannot find any other jumbers related to those pins. From the link that gszakac provided there is a similar problem, but still it cannot help me, so guys HELPP!!

Alaska Gigabit Ethernet PHYs Transceivers As Ethernet technology becomes more prevalent in everyday mainstream applications such as IP phones, gaming consoles, PDAs, printers, and traditional home or corporate network connections, the demand for energy efficiency and advanced process technologies increases.
In the following picture HTG board schematicsmarvsll the Bit[2: Auto-negotiation of Ethernet Marvell 88E chip Finally, the “address bits” to which bus are referred? If you want to achieve great things, then we want to talk with you. The auto-negotiation solution came when I switched SW6 to “” depicted below which makes frequency synthesizer ICS to ouput MHz, as described in ML manual, page 47, table Access comprehensive product specifications for Marvell’s family of Transceivers products:.
Additional features of the Alaska GbE PHYs include a high-level of integration in thermally-efficient packages that optimize PCB real estate and enable fan-less heat-sink-less designs. Also I madvell checked the on-board jumbers that enable the MII mode.
