Bob smith termination

The typical termination for Ethernet ports is called a ‘Bob Smith termination’ and is shown in Figure 6. For ports that are Power-over-Ethernet, this termination network should be modified to block the DC common mode voltage between pairs from creating a large current through the termination resistors, which would blow up the termination ....

Under which conditions can you connect a Bob Smith termination from an Ethernet 8P8C connector to system/circuit ground? Does this always need to be tied to the chassis? What if chassis and circuit ground have been tied together?

Feb 19, 2020 · Ethernet ports are commonly terminated using the “Bob Smith” technique. This termination uses a 75 Ohm resistor for a common mode impedance match at each signal pair, collectively connected via a high voltage 1000pF capacitor to chassis ground. The purpose of this termination is a further reduction in common mode emissions. \$\begingroup\$ Freshman - Hi, You said that you "came across the below schematic image".Please remember the site rule which requires that when a post includes content (e.g. text, image, photo etc.) copied or adapted from elsewhere, the original content must be correctly referenced.
