Claim Text:
1. An apparatus comprising: a switch configured to provide (i) a first signal on a first path when a power signal is not present, (ii) a second signal on a second path when said power signal is present and (iii) a ground signal switchable to said first path when said power signal is present, wherein (i) said first path activates only said first signal and said ground signal, (ii) said second path activates only said second signal, (iii) said power signal is generated in response to an AC service provided to said apparatus and (iv) said ground signal is connected to a power ground through a termination element; a balun circuit responsive to a third signal and configured to amplify and convert said second signal to a differential signal; and a splitter circuit configured to generate a plurality of differential output signals in response to said differential signal, wherein (A) said switch, said balun circuit and said splitter circuit are integrated on a single integrated circuit and (B) said single integrated circuit is configured to maintain a linearity of said amplified second signal over a range of frequencies.
