In one form, a data transmission system includes transmission and reception circuits. The transmission circuit includes a first driver having an input for receiving a first transmit data signal, an output, a positive power supply terminal for receiving an input/output (I/O) power supply voltage, and a negative terminal for receiving an I/O ground voltage, a second driver having an input for receiving the I/O power supply voltage, an output, and a positive power supply terminal for receiving the I/O power supply voltage, and a third driver having an input for receiving the I/O ground voltage, an output, and a negative power supply terminal coupled to the I/O ground voltage. The reception circuit forms a reference voltage based an average of signal content below a predetermined frequency of outputs of the second and third drivers, and receives a signal from the output of the first driver using the reference voltage.

Data transmission with power supply noise compensation

In an printed circuit board on which an integrated circuit die is mounted, an array of plated through holes (PTHs) are formed which include conductive power and ground PTH structures which are connected to provide power and ground reference voltages to the integrated circuit die, and isolated current sensing PTH structures which are formed within sensing proximity to the conductive power and ground PTH structures for sensing current switching activity in the conductive power and ground PTH structures by inductively converting dynamic current changes in the conductive power and ground PTH structures into a measurable voltage signal.
