We are interested to use the X540 Twinville Dual Port 10GbE MAC/PHY in our application. The marketing data sheet


Intel® Ethernet Controllers and PHYs


lists the operating temperature at 0-55C. Yet the data sheet


on pg 1188 lists a maximum case temperature of Tcase Max = 107C.


Please elaborate on the difference and meaning between these two figures. We need the 0-70C temperature range if we are to use this part.


Thank you.
