All claim to use about half the power, are much smaller, and don’t need the 1. The pinout isn’t covered by the NDA, as that information is et10011c published in schematics that you can download.

Gigabit Ethernet PHY without NDA?

Micrel has nothing gigabit on their website. The other problem with these companies is getting smallish numbers of chips is generally expensive and difficult. Plus, all the source code is open as well, so who knows what secret registers that might reveal. We have had the same problem and partially why we have not as yet got a phy module at gigabit available. I mean, what could possibly be NDA-worthy in the datasheet for a 4 year old part that implements a technology GbE which is nearly a decade old?


John Adair Enterpoint Ltd. Besides, I don’t want to reward such bad behavior by these chip companies.

[RFC] etc: Replaced PHY driver by a small dmx board fixup – Patchwork

The schematic merely shows the pinout. Introduction to Microcontrollers Mike Silva. An NDA might be more of a problem for the software; device driver source typically contains information about many of the PHY internal registers. The fact that other users have been forced to redact pages of schematics tells me that this is a serious problem.

Anybody have any experience with it?

Understanding the etc PHY driver

This seems nuts to me. It is cheap, low power, available, and they give out the datasheets without an NDA. Can you imagine how hard it would be to design anything if every chip you used had NDAs attached to it? Et1011d am not a lawyer, and you should read the terms of the NDA very closely.

axe(4) (Belkin F5D5055) problems

For example, I found this schematic containing an 88E in less than a minute of searching: On Dec 17, 2: On 17 Dec, The problem is that all of them et1011x an NDA just to see the datasheet. It has 4 problems: We didn’t think it was worth incorporating in development boards, or modules, if our customers couldn’t get the basic information.


I don’t see how this clashes with open source hardware though. I can only hope these companies stop being so snobbish as they get rapid volume turnoff in the current recession in their favoured consumer markets.
