45 / 47 page  DM9161CI 10/100 Mbps Fast Ethernet Physical Layer Single Chip Transceiver 47 Final Version: DM9161CI-DS-F01 February 22, 2012 9.4.21 Magnetic Selection Guide Refer to Table 2 for transformer requirements. Transformers, meeting these requirements, are available from a variety of magnetic manufacturers. Designers should test and qualify all magnetic before using them in an application. The transformers listed in Table 2 are electrical equivalents, but may not be pin-to-pin equivalents. • Refer to the following tables 5-1 and 5-2 for 10/100M magnetic sources and specification requirements. The magnetics which meet 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 table are electrical equivalents, but may not be pin-to-pin equivalents. Manufacturer Part Number MAGCOM` HS9016, HS9024 Delta LFE8563-DC, LFE8563T-DC Table 5-1: 10/100M Magnetics Sources Parameter Values Units Test Condition Tx / RX turns ratio 1:1 CT / 1:1 - - Inductance 350 μH (Min) - Insertion loss 1.1 dB ( Max ) 1 – 100 MHz -18 dB ( Min ) 1 –30 MHz -14 dB ( Min ) 30 – 60 MHz Return loss -12 dB ( Min ) 60 – 80 MHz -40 dB ( Min ) 1 – 60 MHz Differential to common mode rejection -30 dB ( Min ) 60 – 100 MHz Transformer isolation 1500 V - Table 5-2: Magnetic Specification Requirements |
