The PHYs have to use autonegotiation. I received an email from Micrel yesterday: All rights reserved in the event of the grant of a patent, utility model or design. If you have any progress, let me know.

Well OK, but it doesn’t work Please login or register. This pin have to connect 9 number of KS With or withour cross cable? PHY address offset must be 0? Thank you Mark for your interest.

If only a Link signal is available, this might be used. He told me that this part KS is very mature and he should send me some designs quickly. As you know are the pins datahseet the X high on reset. Does it work with 10MBit mode at Olimex kit?

The PHY addresses should be datzsheet to the logical port number As comparison, there is a binary which runs om this board here: Thank you for your interest.

The phase relation has to be the same each time the PHYs are powered on.

No problem to send packets though, checked with ethereal. ESCs can not regenerate preambles to 8 bytes including SFD because of the on-the-fly processing, received and transmitted preamble length is identical. These tables are incomplete in terms of Ethernet PHY vendors and Ethernet PHY devices — they just give some examples, and it is likely that other devices and devices from different vendors meet the requirements as well.

The Ethernet PHYs were either judged by a brief overview of their data sheets or by additional basic hardware communication tests basic hardware communication tests are indicated in the table. Enhanced Link Detection is generally recommended because additional faults are detected and link loss reaction time is improved.

I don’t know about lead times.

No registered users and 1 guest. The SAM7X has to be carefully controlled during chip startup since its internal pullups cause a bit of a difficulty when the PHY configures itself over the hardware settings read at reset.

Hi David I dwtasheet measured the resistance between the pad 22 and the pin 9. Thanks again Mark, Best Degards, David.

Internal pull-down at MDC. The addresses of Beckhoff’s branch offices and representatives round the world can be datashdet on her internet pages: Problem is at Olimex kit schematic.

On mine, there is a small wire below the chip that I found out when I soldered the chip ks88721. Ok, I finally found something: Hi Mark, I wondered if you have few minutes to check if theses 2 pins are not connected together on your Olimex board. Check out the utasker tutorial for the SAM7X at http:
