20100123488 | DIGITAL PLL WITH KNOWN NOISE SOURCE AND KNOWN LOOP BANDWIDTH - A phase locked loop (PLL) based frequency translator provides a divider augmented with a sigma delta modulator (SDM) in a reference path. The PLL is configured as an all digital PLL and includes a bang-bang phase frequency detector, digital loop filter, and digitally-controlled oscillator. The frequency translator is located in either the reference clock path for division or the PLL feedback loop path for multiplication.

The combination of an integer divider and an SDM yields a fractional divider that divides by N+F/M, where N is the integer portion of the division and F/M is the fractional portion of the division, with M denoting the fractional modulus. Furthermore, since it is desirable to have programmable division factors, it is beneficial to define N, F and M as integers as this simplifies a programming interface when the frequency translator is manufactured as an integrated circuit. | 05-20-2010 |

When the system selects another converted clock signal for use as the dominant clock, the newly selected signal already is edge-synchronized with the dominant clock and, therefore, switchover losses can be avoided. The dominant clock can be subject of further frequency translation processes and output from the system. | 05-20-2010 |
