4.5Extended Temperature Operation with the LXT9785HE

The LXT9785HE provides reliable Ethernet transceiver functionality from -40oC to +85oC. Any LXD9785 demo board supporting a QFP package can support an LXT9785HE mounted and localized extended temperature applied to the LXT9785HE. The LXD9785 demo board components are commercial temperature grade.
