Olin, these days there are DSP cores running at 2400MHz (4 x 600MHz
parallel core) without any radiators with package temperature below
50C.
Do you think a damn ethernet chip which is near 1W  "is not that small" ?
All ethernet chips on the market are sourcing maxim 150mA (some very
old below 50mA), so 250mA in Microchip datasheet is ok for you ?
Why they stopped production a while ago on this chip?

best regards,
Vasile
