Dear Sir,

According to the TDA2x DSP  reference design it uses DP83865+ TDA2X but this PHY DP83865 is a commercial part (0~70degC), do you have another suggestion  for automotive grade part?

Does DP83848 can work with TDA2X DSP?  Thanks.

    I moved this to the forums where they support the TDA2x processor; however, you might want to ask this question on the ethernet forums as well to reach the people who support the DP83848.
