Patent ID: 7463472

Claim:
A circuit for providing surge protection and signal splitting, the circuit comprising: an input configured to received a signal; a current-limiting device having first and second portions, the first portion coupled to the input, the current-limiting device being configured to provide a short circuit between the first and second portions in the absence of an excess current and to provide an open circuit in response to the excess current; a voltage suppression device coupled to the second portion of the current-limiting device and configured to conduct to a ground if a signal received by the voltage suppression device is above a threshold voltage; a signal splitter coupled to the second portion of the current-limiting device and configured to split an incoming signal into multiple output signals; and a plurality of outputs coupled to the signal splitter to receive the output signals; wherein the current-limiting device, the voltage suppression device, and the signal splitter are disposed on a single printed circuit board (PCB).
