An integrated phase accumulator apparatus includes a first phase accumulator, a second phase accumulator, and a switch. The first phase accumulator is configured to accumulate a first phase increment over time and provide a first accumulated phase value for signal generation via a local oscillator at a first frequency. The second phase accumulator is configured to accumulate a second phase increment over time and provide a second accumulated phase value for signal generation via the local oscillator at a second frequency. The switch is configured to switch the integrated phase accumulation apparatus between the first frequency and the second frequency and between the second frequency and the first frequency so as to maintain a first continuous phase for the first frequency and a second continuous phase for the second frequency.
