Hey Guys,
I had some questions regarding the DP83848Q-Q1. I was wondering how this device was tested to meet IEEE standards. Let em explain in more detail. So I am looking to test the physical layer of Ethernet on our new product and when I reached out to some compliance meeting companies which test 10Base - T and 100Base -TX they said that for to test the physical layer I would need a bunch of things that they could provide, but they mentioned that I would need low-level drivers.
So everyone who tests an Ethernet PHY needs to place the PHY into specific compliance test modes for each test outlined in the ANSI X3.263-1995 standard specification. In order to place the PHY into these necessary modes, low-level drivers are needed, and must be provided by the PHY vendor.
If the PHY vendor's part has been qualified as compliant per the Ethernet standard, then this means that the PHY vendor has already placed their PHY into the required test modes required by the standard and by definition must have drivers available to support it.
So I'm contacting you guys to ask to speak with the engineers who originally qualified the TI Ethernet PHY that I am using. If TI has qualified the part as compliance per the Ethernet standard, then they must have created drivers for placing the PHY into the required modes.
As an example, to place an Intel network interface card used in our scope into the required compliance test modes, Intel provided us with GIGCONF.exe which run from MSDOS and provides a menu selection for placing the DUT into the needed modes.
So let me know what you guys think.
