Industry-leading PCI Express Clock Solutions

IDT has a history of firsts in PCI Express clocking and timing with the first PCIe Gen1, Gen2, Gen3 and Gen4 clocking solutions; the industry's first very-low power PCI Express clock generator (1.8V); and the industry's first ultra-low-power PCI Express clock generator (1.5V), which is the world's lowest power PCIe clock generator. Now the Gen5-ready family of PhiClock™ programmable clock generators and portfolio of enhanced 9Z clock buffers continue the legacy with higher performance and lower power consumption for PCIe systems.

Whether your system is architected using the popular common-clocked architecture, the less prevalent separate reference clock with no SSC (SRNS), or the newly proposed separate reference clock with independent SSC (SRIS) architecture, we have the optimal PCI Express clock solution to meet your needs. Find your ideal PCI Express clock generator, synthesizer, buffer, or multiplexer from IDT's large selection of PCIe clocks.

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. IDT's 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.
