Renesas Electronics Corporation expanded its timing solutions portfolio with a new ultra-low 25fs-rms clock solution for wireline infrastructure, data center and industrial applications. The new FemtoClock™ 3 family includes ultra-low jitter clock generators and jitter attenuators with 8 and 12 outputs, enabling high-performance, easy-to-use, and cost-effective clock tree designs for next-generation, high-speed interconnect systems. Target applications for the new devices include telecom switches and routers, top-of-rack data center switches, medical imaging, broadcast audio & video and more.
FemtoClock 3 devices provide industry leading phase noise and jitter required to meet the needs of 112Gbps SerDes rates, as well as next generation 224Gbps SerDes designs using commonly available 48MHz to 73MHz crystals. The highly integrated devices can generate up to four frequency domains and offer integrated LDOs (Low Drop Out regulators) with superior PSRR, reducing board complexity and cost (more info).
