WebAuto MDIXAutomated detection of MDI and MDIX devices BSTBob Smith Termination – BST is integrated in most RJ45 Jacks. This network provides a matching impedance to the common-mode characteristic impedance of a Cat5 cable, which prevent the cable acting as a resonant antenna. WebIn practice, great care must be taken to separate these pairs as 10/100-Mbit/s Ethernet equipment electrically terminates the unused pins ("Bob Smith Termination"). [18] Shared cable is not an option for Gigabit Ethernet as 1000BASE-T requires all four pairs to operate. Single-pair [ edit] WebJun 19, 2015 · @IC_designer_Rimpelbekkie - the Bob Smith termination is for common mode signals on ethernet lines and not for direct termination.

WebData transfer between MAC and PHY is via the Reduced Gigabit Media Independent Interface (RGMII) for 1000Base-T, 10Base-T, and 100Base-TX. The RTL8211F(I)-CG supports various RGMII signaling voltages, including 3.3, 2.5, 1.8, and 1.5V. WebApr 12, 2024 · A final degree of protection comes from the “Bob Smith” termination. This uses a 75-ohm (Ω) resistor to implement a common-mode impedance match for signal pairs collectively connected via a capacitor to ground. The termination can help reduce the common-mode emissions discussed later (Figure 2).
