The MAX3639 is a highly flexible, precision phase-locked loop (PLL) clock generator optimized for the next generation of network equipment that demands low-jitter clock generation and distribution for robust high-speed data transmission. The device features subpicosecond jitter generation, excellent power-supply noise rejection, and pin-programmable LVDS/LVPECL output interfaces. The MAX3639 provides nine differential outputs and one LVCMOS output, divided into three banks. The frequency and output interface of each output bank can be individually programmed, making this device an ideal replacement for multiple crystal oscillators and clock distribution ICs on a system board, saving cost and space.

This 3.3V IC is available in a 7mm x 7mm, 48-pin TQFN package and operates from -40°C to +85°C.
