The SKY63104/5/6 family of jitter attenuating clocks and the SKY62101 clock generator are the industry’s first clock devices that can simultaneously provide ultra-low jitter reference clocks for 224G PAM4 Ethernet SerDes with 18fs RMS phase jitter, while generating PCIe Express (PCIe) Gen 1/2/3/4/5/6/7 compliant reference clocks with spread spectrum.
