Low-Voltage DC Coupling Circuits
For applications where power line communication on ≤48V low-voltage DC power lines is required (for example, 12V
automotive systems) the coupling circuit can be simplified by removing the high-pass filter components L101 and C101
as shown in Figure 4.27. Component values and part numbers for this circuit are shown in Example 11 in this chapter.
