Abstract
A bitstream analysis circuit, generates a reference clock control data. A reference clock DPLL receives a system clock signal and reference clock control data from the analysis circuit and generates a reference clock signal. The reference clock DPLL comprises a 1/n frequency dividing circuit for frequency-dividing the system clock signal, and a 1/(n+1) frequency dividing circuit for frequency-dividing the system clock signal. A register stores data to set frequency dividing ratios of both frequency dividing circuits. A mixing ratio set register stores data to set a mixing ratio between output clock signals from both frequency dividing circuits and a mixing circuit, and mixes the output clock signals from both frequency dividing circuits at a mixing ratio in response to the data in the mixing ratio setting register.
