Is my Bob Smith termination valid for Ethernet 100 Mb s? A "Bob Smith" circuit is also necessary to prevent shorts in a Power-over-Ethernet (PoE) situation 75ohm was standard termination when coax was used for ethernet the capacitor is necessary to block DC from ground for PoE situations
Bob Smith termination for Ethernet magnetics I know that Bob Smith termination is recommended for Ethernet differential pairs Please refer the below image for Bob Smith termination resistor placement As far as I know, Bob Smith termination
Modified BoB smith termination for PoE-- Will it work? To increase the power handling capacity through the bob smith termination during surge condition, we are purposely added one more 10nF+75Ω termination resistor combination along with the existing each 10nF+75Ω termination combination Will this scheme affect the cable characteristic impedance matching scheme?
Connecting a PHY to another PHY on a same board Generally, if I'm connecting a PHY to RJ45 connector, I would add center tap capacitors and Bob-Smith termination like below But if I am connecting a PHY to another PHY, do I still need the Bob-Smith termination?
