9DBU PCIe Clock Buffers

Renesas Electronics 9DBU PCI Express® (PCIe) Clock Buffers are ultra-low-power PCI Express buffers that operate from a 1.5V supply voltage. Designed to use the same supply voltage as modern systems-on-chip (SoCs) and field-programmable gate arrays (FPGAs), 9DBU Clock Buffers enable designers to consolidate power rails, which reduces system complexity, physical size, and power consumption. The ultra-low power consumption reduces heat dissipation to ease cooling requirements. These clock buffers meet PCIe Gen 1, Gen 2, and Gen 3 performance requirements and can be reused through several generations of products. Renesas / IDT offers the 9DBU PCI Express Clock Buffers in 2 to 9-output configurations with and without non-PLL fan out and PLL zero-delay-buffer modes to address virtually any PCIe application.
