Abstract
An inkjet printhead that has a support member, and a plurality of printhead IC'"'"'s mounted adjacent each other on the support member. Each of the printhead IC'"'"'s has an array of nozzles for ejecting drops of printing fluid onto a media substrate, and drive circuitry for driving the array of nozzles. A print engine controller (PEC) sends print data to each of the printhead IC'"'"'s and the drive circuitry extracts a clock signal from the data transmission from the PEC.
