    • A multiplexer circuit, system and method is provided herein for multiplexing signals with reduced jitter by eliminating all crosstalk and power supply noise injection within the multiplexer circuit. For example, crosstalk and supply noise injection may be eliminated by: (i) separating the multiplexing function into three separate logic gates and (ii) allowing only one switching input per logic gate, hi some cases, jitter may be further reduced by distributing the logic gates across three distinct power domains, hi other words, the logic gate inputs may be further isolated by gating each signal in its own power domain. In addition, the multiplexer circuit provides built in delay matching by utilizing three substantially identical logic gates.

    • A method for synchronously executing a plurality of commands generated by a first module and executed at a second module, wherein the first and second modules communicate through a communication link, is provided. The method includes generating the commands at the first module, transmitting the commands through the link to the second module, and associating the execution time of the commands with an independent event at the second module. When the independent event is detected, the commands are executed synchronously at the second module. The method can be specifically applied to a baseband processor controlling a camera through a camera interface module, wherein the processor and the camera interface module are connected through an MDDI link. An example of a baseband processor controlling a camera through a Pathfinder camera module interface module is described. Specific built-in mechanisms of the camera module interface that enable flexible implementation of the method are also provided.
