Serial communication device for i2c or i3c communication and method

A serial communication device for I2C or I3C communication, the serial communication device comprising:

• a serial data (SDA) terminal coupled to a series arrangement of a SDA filter and a SDA programable delay circuit ;
• a serial clock (SCL) terminal coupled to a series arrangement of a SCL filter and a SCL programable delay circuit;
• a SCL delay counter and a SDA delay counter;
• an oscillator coupled to the SCL delay counter and the SDA counter;
• and
• logic circuitry configured to:
• detect a start condition;
• enable the oscillator to provide a clock to a first counter to count to a first count value during a first time duration corresponding to a SDA filter propagation delay time;
• enable the oscillator to provide a clock to a second counter to count to a second count value during a second time duration corresponding to a SCL filter propagation delay time;
• and
• program a delay of at least one of the SDA programable delay circuit and the SCL programable delay circuit determined from the first count value and the second count value.
