DP83826AE: Incorrect documentation

Hi,

I'm finding STRAP7 pulled to 1 is setting phy address 0, to 1, not 0. -> This is a typo on our part, I am working on update the 826A datasheet to correct this mistake.

Additionally, the PHY_ID is returning 0x2000a110, not 0x2000a136. -> Can you please share the top marking of the part? I want to make sure we do have the latest 826A silicon.

Thanks

David

Hi David,

Markings are:
826AE

TI 538

AG73 G4

Hi,

Thanks for the info. I requested some 826AE parts and let me test them on my board.

Thanks

David

Hi,

I checked and the correct PHY_ID for 826A is 0x2000A134. Are you reading 0x2000a110 from multiple units?

Thanks

David

Hi David, yes, each of the boards reports that number.

I noticed the PHY_ID table has a mask with each number, 0xfffffff0, so I suppose it's ignoring the bottom 4 bits, but then I'd still expect 0x2000A130, not 0x2000a110.

Hi,

Any chance you can ship me couple units?

Thanks

David

Hi David,

Could I just ship you one of the chips?

As a sanity check, I ran mdio tools to dump the info, it's 0x2000a114 on our boards.

Hi,

I read the PHY ID again on the DP83826A EVM, and below are the return values.

Can you please accept my friendship request so I can send you my mailing address?

Thanks

David
