DP83869EVM: DP83869HM vs DP83869EM

Yuto Kitamura

Part Number: DP83869EVM
Other Parts Discussed in Thread: DP83869

Dear team,

I see that DP83869EMRGZT in the BOM of DP83869EVM.

I found several e2e posts about this topic but the answer is different.

I think the big difference is VDD1P1, 1.1V and 1.0V.

In addition, 1.0V cannot be used for -HM because according to D/S 1.1V +/-10% is needed.

My customer evaluated and tries to adopt it but they must use 1.0V as same as EVM because they also use 1.0V for FPGA.

Can they buy DP83869EMRGZT as production?

Or do they have to use 1.1V with -HM?

Best regards,

Yuto

Hi Yuto,

The DP83869EM is not available for purchase. You must follow datasheet to guarantee results.

What happens in customer system when they use 1.0V where it requires 1.1V?

1.0V is still within 10% of 1.1V.

Hi Alon,

1.0V is still within 10% of 1.1V.

I know it is, but there is no margin in this condition.

Hi Yuto,

I agree completely, that is not an ideal situation, however, our option are limited as the DP83869 spec is 1.1V. Could customer generate 1.1V?

The DP83869 spec was revised and now takes 1.1V, the part number mentioned in EVM BOM sheet is a part that is not possible to buy.

Best,

Alon
