Clock Generator With Subpicosecond Jitter Replaces Expensive Crystal Oscillators

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 fre- quency and output Interface of each output bank CAN be individually programmed, making this device an ideal replacement for multiple crystal Oscillators and Clock dis- tribution 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. By Maxim Integrated Products
