Renesas introduces the new FemtoClock™ 3 clock solution that combines ultra-low power consumption with superior 25fs-rms jitter performance

     Renesas Electronics is expanding its clock solutions portfolio with the introduction of FemtoClock™ 3, a new ultra-low 25fs-rms clock solution for wired infrastructure, data centers and industrial applications. The new family of 8 - and 12-way differential output ultra-low jitter clock generators and jitter attenuators enables high-performance, easy-to-use, and cost-effective clock tree designs for next-generation high-speed interconnect systems. Target applications for the new products include telecommunications switches and routers, rack-mounted data center switches, medical imaging, broadcast audio and video, and more.

     The FemtoClock 3 product features industry-leading ultra-low phase noise and jitter to meet the needs of 112Gbps SerDes rates and the next generation of 224Gbps SerDes designs at passive crystal inputs at 48MHz to 73MHz frequencies. The highly integrated product can have up to four clock domains and offers an integrated LDO (Low voltage differential regulator) with excellent signal-to-noise ratio (PSRR), reducing board complexity and cost.

     Zaher Baidas,Vice President of the Timing Division for Renesas, said: "With decades of experience and patented technology, Renesas Electronics is committed to providing high-quality clock solutions that drive the advancement of the industry. "By enabling ultra-low jitter multi-clock and synchronization in a single device, the FemtoClock 3 product greatly optimizes PCB design, reduces solution area and cost, and supports continued industry development and innovation."

     Vincent Ho, CEO at UfiSpace, said: "The FemtoClock 3 is a clock solution that gives us ultra-low jitter performance while maintaining low power consumption, optimizing the printed circuit board design and reducing the PCB area of our next generation switch solution. With clock solutions built by Renesas, we have the ability to deliver advanced products in an efficient and cost-effective manner."

     FemtoClock 3 supports several modes of operation, including synchronization, jitter attenuation, and clock generation. Customers can combine the new FemtoClock 3 solution with Renesas clock solutions such as ClockMatrix™, VersaClock, clock drivers and active crystal to meet the demanding, high-reliability and complex clock design needs of high-performance wired infrastructure and data centers.

     FemtoClock 3 integrates seamlessly with the Renesas IC Toolbox (RICBox) application, enabling users to configure and program components on the evaluation board. In addition, RICBox can be connected to Renesas Lab on the cloud platform, giving users the ability to connect virtually to a real lab environment.
