  • DIGITAL SUPPRESSION OF SPIKES ON AN I2C BUS
    Publication number: 20100244919
    Abstract: An apparatus that is adapted to receive signals from an Inter-Integrated Circuit (I2C) bus is provided. The apparatus comprises a serial data (SDA) filter, a serial clock (SCL) filter, I2C interface logic, and operational circuitry. The SDA filter is adapted to receive an SDA signal from the I2C bus and includes a hold terminal and a disable terminal. The hold terminal of the SDA filter issues a disable signal when a transient in the SDA signal is detected. The SCL filter is adapted to receive an SCL signal from the I2C bus and includes a hold terminal and a disable terminal. The hold terminal of the SCL filter issues a disable signal when a transient in the SCL signal is detected. Additionally, the hold terminal of the SCL filter is coupled to the disable terminal of the SDA filter, and the hold terminal of the SDA filter is coupled to the disable terminal of the SCL filter.
