Description

The 9FGL6251 is an intelligent buffer/clock generator tailored for single and dual-ported nVME SSDs. It supports Common (CC) and Independent Reference (IR) clocking architectures and is ideal for U.2 and M.2 form factors. The device is also useful in PCIe master/slave and clock multiplexing applications, with an internal clock generator as a third input channel.
