ABSTRACT:
A circuit for providing surge protection and signal splitting includes 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 outputs coupled to the signal splitter to receive the output signals.
