I have an ethernet connector whose chassis or shield ground that I need to connect it to the digital ground. I read that it is a practice that is followed in many designs.
- Why should they be connected together? Any reasons? What would happen if they are not connected?
- Also, in some designs 100nF and 50V capacitors are used to connect both the grounds. In some cases, I see 330ohm or 0ohm resistors? Whereas, in some designs, I see both Resistor and capacitor are used in parallel to connect both the grounds. Can someone tell me the pros and cons of each connection to arrive at a good circuit connection.
