Abstract
A frequency generation circuit includes an oscillator ( ), a comparator ( ) coupled to the oscillator, a first divider ( ) coupled to the comparator, a PLL ( ) coupled to the first divider, a second divider ( ) coupled to the PLL, a first multiplexor ( ) coupled to the second divider, a third divider ( ) coupled to the comparator and the first multiplexor, a second multiplexor ( ) coupled to the comparator and the reference clock PLL, a fourth divider ( ) coupled to the second multiplexor, a fifth divider ( ) coupled to the comparator, and a seventh divider ( ) coupled to the comparator. A method of operating a transceiver includes using the frequency generation circuit to provide a first clock signal, a second clock signal, a first reference frequency, and a second reference frequency for a first component, a second component, a third component, and a fourth component, respectively, of the transceiver.
