Abstract
The present invention includes a circuit assembly and method of synchronizing plural circuits. According to one aspect of the present invention, a circuit includes: an oscillator configured to generate a reference clock signal; a first circuit including: a first divider configured to generate a first internal clock signal responsive to the reference clock signal; and reset generation circuitry configured to receive an external reset signal and generate a reset second circuit signal synchronized with a predefined position of the first divider, with the reference clock signal and with the external reset signal; and a second circuit including: reset detection circuitry configured to generate a reset detection signal synchronized with the reset second circuit signal and the reference clock signal; and a second divider configured to set to a predefined position responsive to the reception of the reset detection signal and generate a second internal clock signal synchronized with the first internal clock signal.
