Abstract
A fast frequency hopping implementation in a phase lock loop (PLL) circuit achieves a PLL lock to a new frequency in a very short period of time. In one instant, frequency allocation at a transceiver is changed. In response, a local oscillator frequency hops to a new center frequency based on the changed frequency allocation. The hopping to the new center frequency is based on two-point modulation of a phase locked loop.
