Renesas Electronics 9DBL0x Fanout Buffers

Renesas Electronics 9DBL0x Fanout Buffers are low-power, high-performance, and support PCIe Gen1 through Gen5. These buffers feature 2 to 8 Low-Power HCSL (LP-HCSL) outputs, 1MHz to 200MHz operation in fan-out mode, and three selectable SMBus addresses. The 9DBL0x fanout buffers also support PCIe clocking architectures such as Common Clocked (CC) and Independent Reference (IR) with and without spread spectrum (SRIS and SRNS). Typical applications include PCIe riser cards, nVME storage, networking, accelerators, and industrial control/embedded.
