Module manager for wide-array inkjet printhead assembly

An inkjet printhead assembly, comprising:

• multiple inkjet printhead modules, each inkjet printhead module including:
• a carrier;
• N printheads disposed on the carrier;
• and
• a module manager disposed on the carrier and adapted to receive a serial input data stream and corresponding input clock signal, which has active edges at a defined frequency, from a printer controller located external from the inkjet printhead assembly, the module manager including:
• a clock generator adapted to receive the input clock signal and to provide N output clock signals, each having active edges at a frequency N times slower than the defined frequency and being provided to a corresponding one of the N printheads:
• and
• N registers each adapted to receive the serial input data stream and a corresponding one of the N output clock signals and to provide one of N serial output data streams to a corresponding one of the N printheads.

A method of operating an inkjet printhead assembly comprising:

• receiving, at a module manager disposed on a carrier, a serial input data stream and a corresponding input clock signal, which has active edges at a defined frequency, from a printer controller located external from the carrier;
• providing, from the module manager, N output clock signals based on the input clock signal, wherein each output clock signal has active edges at a frequency N times slower than the defined frequency and is provided to a corresponding one of N printheads disposed on the carrier;
• receiving at the module manager, the serial input data stream into N registers;
• controlling each of the N registers with a corresponding one of the N output clock signals;
• and
• providing, from each of the N registers, one of the N serial output data streams to a corresponding one of the N printheads.
