40G/100G Ethernet

For designers of next generation 40G / 100G Ethernet systems, high performance FPGAs typically require a variety of high performance timing solutions, including programmable XOs, jitter attenuating clocks, and clock generators. Our Si570 programmable XO is an ideal solution in this application since it offers easy I2C programming and sub picosecond reference clock generation for the Si5368/69 jitter attenuators and Si5335 clock generators.

With its programmable loop bandwidth, our Si5368/69 precision clock generators provide and ideal solution to jitter cleaning of the recovered network I/F clocks. Finally, with its sub-picosecond jitter and industry-leading PSRR performance, our Si5335 quad clock generator simplifies the PCB by replacing numerous XOs needed by the memory and high speed serial interfaces provided by the FPGA.
