A 65-nm videocontroller synthesizer for monitors with resolution up to 4K
The paper highlights the design process of clock synthesizer for videocontroller implementation based on phase-locked loop (PLL) with autoshifting circuit and programmable charge pump (CP). An architecture of synthesizer for interface clock frequency with step 250 kHz and less without delta-sigma modulator, phase interpolator and randomizator in the feedback loop has been proposed.
