Abstract
A system is provided for generating an output clock used for N.5 modulus division. An edge-slip circuit accepts a modulus count, a divisor select signal, and a clock signal having a frequency greater than a modulus count frequency. The edge-slip circuit also has an input to accept an output clock signal, and an output to supply a clock slip signal (NE). An exclusive-or (XOR) has an input to accept a buffered clock signal (NF) and the clock slip signal (NE). The XOR has an output to supply the output clock signal. The output clock signal has a frequency equal to a buffered clock signal frequency, with no skipped clock edges, when the clock slip signal does not change logic levels. Alternatively, the output clock signal frequency is equal to the buffered clock signal frequency, with a skipped clock edge, when the clock slip signal changes logic levels.
