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.

“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 synchronization 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.”

Key Features of the FemtoClock 3 Family

Industry-leading 25fs-rms jitter exceeds next-generation 112Gbps and 224Gbps SerDes reference clock requirements
Up to 4 frequency domains allow all system clocks to be generated from a single device
Device variants with jitter attenuation, synchronization and clock generation capabilities and with 8 or 12 outputs
Low power dissipation of 1.2W and operating a single 1.8V supply
Integrated non-volatile memory allows for device customization in factory at no additional cost to customer
Small 7 x 7mm 48-pin VFQFPN and 9 x 9mm 64-pin VFQFPN packages
Compliant with ITU-T G.8262 and G.8262.1 for enhanced synchronous Ethernet
Single chip with multiple operating modes simplifies overall clock tree

FemtoClock 3 supports multiple operating modes, including synchronization, jitter attenuation, and clock generation. Customers can combine the new FemtoClock 3 solution with the broader ClockMatrix™, VersaClock, buffer and oscillator portfolio of timing solutions to address challenging timing needs for their high-performance wireline infrastructure and data center designs.

FemtoClock 3 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. Additionally, RICBox interfaces with the Renesas Lab on the Cloud platform, providing users with the capability to connect virtually to an actual laboratory setting.
