Industry-leading PCI Express Clock Solutions
Renesas has a history of firsts in PCI Express clocking and timing:
- PCIe Gen1, Gen2, Gen3, Gen4 and Gen5 clocking solutions
- Very-low power PCI Express clock generator (1.8V/1.5V)
- Ultra-low power HCSL outputs to replace standard-HCSL outputs for power savings up to 85%
- Dynamic frequency control for over/under clocking and margining
- Incorporation of multiple PLLs in a single device to save power and board space
Renesas' expertise in leading CPU platforms supports all your design needs for processor clocking from personal PCs to cloud servers. Find your ideal solution of clock generators and buffers to motherboard clock generators or motherboard clock buffer.
Renesas recognizes that meeting strict requirements from tight jitter limits, BOM costs and board space can be challenging. We help you to meet requirements including PCI Express, SATA, USB, SAS, DMI, QPI, Hypertransport, Ethernet, etc., and the multiple socket CPU architectures.

About PCI Express Clocks
PCI Express is the one of the most widely used high-performance peripheral interfaces in the world. From its origins in graphics, fields as diverse as high-performance computing, servers, storage, networking, instrumentation and consumer have adopted PCI Express. This broad application space requires multiple PCI Express clock solutions optimized for the different performance, BOM cost and board-space tradeoffs that each application demands. Renesas' strong position with leading computing, networking and consumer customers and our participation on the appropriate standards bodies allows us to offer the ideal PCI Express clock and timing solutions (in short, PCIe clocks) for any application.
