Abstract:
A system and method for synchronizing multiple integrated circuit (IC) chips for an input device having a display device integrated with a capacitive sensing device. A first one of the IC chips is a master IC chip and a second one of the IC chips is a slave IC chip. The master IC chip is configured to transmit synchronization signals to and from the slave IC chip, such that capacitive frames are acquired by each of the IC chips at substantially the same time, the initiation of the sensing signals is synchronized for each of the IC chips and the clock signals of the slave IC chips are synchronized with the clock signal of the master IC chip.
