General Description

The 9FGL6241 / 9FGL6251 are intelligent buffer/clock generators tailored for single and dual-ported nVME SSDs.

They support Common (CC) and Independent Reference (IR) clocking architectures and are ideal for U.2 and M.2 form factors.

The devices are also useful in PCIe master/slave and clock multiplexing applications, with an internal clock generator as a third input channel.
