Abstract
A numerically controlled oscillator (NCO) module includes a first accumulator circuit, a second accumulator circuit, and a phase-to-amplitude converter module. The first accumulator circuit receives a clock signal and at least first portions of each of multiple frequency control words and accumulates the first portions to generate a phase value. Each of the frequency control words identifies a fractional value and includes a respective one of the first portions and a respective second portion. The second accumulator circuit accumulates the second portions and generates a trigger signal based on a result of the accumulated second portions. The first accumulator circuit is configured to adjust the phase value based on the trigger signal. The phase-to-amplitude converter module generates a digital signal based on the clock signal and the phase value. An output transmits an output signal from the NCO module based on the digital signal.
