Patent ID: 8155352

Claim:
A serializer/deserializer comprising: an audio amplifier and processor arranged to interface, at least, with a microphone and a speaker; a deserializer arranged to receive first serial signals and to output first parallel signals to displays and to the audio amplifier and processor; a serializer arranged to input second parallel signals from a keypad matrix of multiple keys, cameras, and the audio amplifier and processor, and to output second serial signals; wherein the audio amplifier and processor interfaces with the serializer and the deserializer to send and to receive parallel data therefrom; a flexible cable arranged to carry signals to and from a second system, wherein the first serial signals are carried to the deserializer via the flexible cable, and the second serial data signals are carried from the serializer via the flexible cable, a key sense circuit that outputs a first signal when any one of the multiple keys is depressed; and a first power up circuit that detects the first signal and outputs a power up signal that turns on power to the serializer/deserializer.
