Our clock generator ICs covering a wide variety of applications. Maxim's clock ICs achieve industry-leading jitter and meet all wireline networking standards.

Our clock multiplier ICs offer a precise, economical and reliable timing solution for reducing electro-magnetic interference (EMI) radiation, and to ensure EMI standards compliance. Our pin-programmable clock multipliers generate a wide range of clock frequencies (8MHz to 134MHz) from a single external crystal. Dithered spread-spectrum output significantly reduces EMI emissions. Pin-selectable dither magnitude and rate allows real-time adjustment of dither settings.
