67 / 70 page ![]() Final 67 Version: DM9102D-DS-F01 May 10, 2006 9.7 Magnetics Selection Guide • Refer to the following tables 9-1 and 9-2 for 10/100M magnetic sources and specification requirements. The magnetics which meets these requirements are available from a variety of magnetic manufacturers. Designers should test and qualify all magnetic specifications before using them in an application. The magnetics listed in the following tables are electrical equivalents, but may not be pin-to-pin equivalents.
