New timing solution delivers industry’s lowest power and leading jitter performance

Renesas Electronics Corporation has expanded its timing solutions portfolio with a new ultra-low 25fs-rms clock solution for wireline infrastructure, data centre and industrial applications. The new FemtoClock 3 family includes ultra-low jitter clock generators and jitter attenuators with eight and 12 outputs, allowing high-performance, easy-to-use, cost-effective clock tree designs for next-generation, high-speed interconnect systems. Target applications for the new devices include telecom switches and routers, top-or-rack data centre switches, medical imaging, broadcast audio and video and more.

The devices provide industry-leading phase noise and jitter needed to fulfil the requirements of 112Gbps SerDes rates and next-generation 224Gbps SerDes designs using commonly available 48MHz to 73MHz crystals. The highly integrated devices can generate up to four frequency domains and provide integrated LDOs with superior PSRR, reducing board complexity and cost.

“Renesas leads the industry with best-in-class timing solutions built from decades of experience and patented technology,” said Zaher Baidas, vice president of the Timing Division for Renesas. “FemtoClock 3 devices extend that leadership by providing multiple clock and synchronisation functions in a single device with ultra-low jitter, simplifying printed circuit board design and reducing solution area and cost.”

“FemtoClock 3 was the only timing solution that offered us the ultra-low jitter performance while maintaining low power dissipation and simplifying the PCB design and lowering solution area on our next-generation switches,” said Vincent Ho, CEO at UfiSpace. “We count on Renesas to deliver the timing solutions that enable us to deliver leading-edge products quickly and cost-effectively.”

The solution supports multiple operating modes, including synchronisation, jitter attenuation, and clock generation. Customers can combine the new solution with the broader ClockMatrix, VersaClock, buffer, and oscillator portfolio of timing solutions to meet challenging timing needs for their high-performance wireline infrastructure and data center designs.

The solution functions seamlessly in conjunction with the state-of-the-art Renesas IC Toolbox (RICBox) application, empowering users to configure and program devices on the evaluation board. Also, RICBox interfaces with the Renesas Lab on the Cloud platform, allowing users to connect virtually to an actual laboratory setting.
