The wide range of interfaces in today’s computing systems (PCI Express, SATA, USB, SAS, DMI, QPI, Hypertransport, Ethernet, etc.), and the multiple CPU architectures (Intel, Freescale, etc) demand a daunting array of tradeoffs in areas of performance, BOM cost, and board space. Renesas has the longest standing relationship with the industry’s leading CPU and compute vendors to offer both the largest portfolio of reference clock solutions and value-added clocks that provide customer-optimized tradeoffs.
Renesas is a leading innovator in the compute timing space with many firsts including: first to introduce low power HCSL outputs to replace standard-HCSL outputs for power savings up to 85%; first to provide dynamic frequency control for over/under clocking and margining; first to incorporate multiple PLLs in a single device to save power and board space. Renesas takes pride in offering motherboard clock and server clock solutions that best fit your particular design. Find your ideal computing clock solution by browsing the devices listed below.
