Abstract

An apparatus and method for demultiplexing a time-multiplexed signal are described. The time-multiplexed signal is a combination of component signals, each of which is modulated at a unique modulation frequency. The demultiplexer of the system includes an input interface over which the signal is received. One or more modulators receive the multiplexed signal and demultiplex the signal in stages. A plurality of receivers are used to detect clock and data from the component signals. Each of the receivers is tuned to a respective one of the modulation frequencies of the component signals. One or more of the receivers provides one or more feedback signals to a bias input and/or an RF input of one or more of the modulators. The feedback signals are used to adjust the modulators such that the power at the receiver at the associated modulation signal is maximized, thus causing the modulators to route each of the demultiplexed component signals to the appropriate receiver.
