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.

Key Features of the FemtoClock 3 Family: 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 VFQFP N 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 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. Renesas has combined FemtoClock 3 with numerous compatible devices from its portfolio to offer winning Combinations, including the 1600G Fixed Form Factor Switch.

winning Combinations are technically vetted system architectures from mutually compatible devices that work together seamlessly to bring an optimized, low-risk design for faster time to market. Renesas offers more than 400 Winning Combinations with a wide range of products from the Renesas portfolio to enable customers to speed up the design process and bring their products to market more quickly.
