Abstract:
1. An integrated circuit, comprising: a first output driver; a first connecting pad connected to said first output driver and outputting a first digital signal; a second output driver; a second connecting pad connected to said second output driver and outputting a second digital signal; a connection for a time reference signal; a receiver circuit having a first input connected to a junction between said first connecting pad and said first output driver, a second input connected to a junction between said second connecting pad and said second output driver, and an output; a device for assisting in matching propagation times of signals present on said first and second inputs of said receiver circuit, said device connected between at least one of said first and second inputs and at least one of said first and second output drivers; and an assessment circuit for measuring and assessing a phase shift between an applied signal and the time reference signal, said assessment circuit having a first input connected to said output of said receiver circuit, a second input connected to said connection for the time reference signal, and an output for outputting a measured result.
