  • Patent number: 11474635
    Abstract: An input device comprises a plurality of sensor electrodes and a processing system coupled to the plurality of sensor electrodes. The processing system comprises a sensor driver. The sensor driver comprises clock synchronization circuitry, a blocking pulse generator, and a sensor module. The clock synchronization circuitry is configured to receive an external clock signal, and synchronize an internal clock signal with the external clock signal. The blocking pulse generator is configured to generate a first blocking pulse based on the internal clock signal. The sensor module comprises sensing circuitry and is configured to pause acquisition of a resulting signal from a sensor electrode based on the first blocking pulse.
