Abstract
Apparatus, systems, methods, and articles may divide a frequency associated with an output of an oscillator formed in a semiconductor substrate using a programmable fractional-N divider module (PFNDM) coupled to the oscillator. A calibration module may be coupled to the PFNDM to select the division ratio to yield a first clock signal of an estimated frequency. Other embodiments may be described and claimed.
