I don’t see how this clashes with open source hardware though.

The schematic merely shows the pinout. For example, I found this schematic containing an 88E in less than a minute of searching: Et10111c is cheap, low power, available, and they give out the datasheets without an NDA.

Create free account Forgot password? The problem is that all of them require an NDA just to see the datasheet. Plus, all the source code is open as well, so who knows what secret registers that might reveal. The pinout isn’t covered by the NDA, as that information is already datsheet in schematics that you can download. Sign in Sign in Remember me Forgot username or password?


John Adair Enterpoint Ltd. The fact that other users have been forced to redact pages of schematics tells me that this is a serious problem.

Gigabit Ethernet PHY without NDA?

This seems nuts to me. 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?

Anybody have any experience with it? 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.

Dataasheet other problem with these companies is getting smallish numbers of chips is generally expensive and difficult. We have had the same problem catasheet partially why we have not as yet got a phy module at gigabit available. 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. All claim to use about half the power, are much smaller, and don’t need the 1.

Besides, I don’t want to reward such bad behavior by these chip companies. I am not a lawyer, and you should read the terms of the NDA very closely. An NDA might be more of a problem for the software; device driver source typically contains information about many of the PHY internal registers. Introduction to Microcontrollers Mike Silva.

On Dec 17, 2: Can you datasheey how hard it would be to design anything if every chip you used had NDAs attached to it?

I have found candidates from Marvell, Vitesse, and Broadcom. Micrel has nothing gigabit on their website. On 17 Dec,
