Claim 0:
1. An apparatus comprising:
a multi-modulus divider (MMD) having a divider input, a divisor input, and a divider output;
a phase detector having a first clock input a second clock input, and a PD output, the second clock input coupled to the divider output; and
a phase to digital converter (P2DC) having a P2DC input and a P2DC output, the P2DC input coupled to the PD output, and the P2DC output coupled to the divisor input, the P2DC including a filter and an analog to digital converter (ADC) coupled between the P2DC input and the P2DC output, the ADC configured to provide a digital signal representing a frequency ratio between a first clock signal at the divider input and a second clock signal at the first clock input.
