The 5V41067A is a 2:4 differential clock mux for PCI Express applications. It has very low additive jitter making it suitable for use in PCIe Gen2 and Gen3 systems. The 5V41067A selects between 1 of 2 differential HCSL inputs to fanout to 4 differential HCSL output pairs. The outputs can also be terminated to LVDS.

PCIe Clocking Architectures (Common and Separate)

This is the first video in our PCIe series. In this video, we define PCIe architectures, focusing on common and separate clock architectures. Watch the rest of the video series below where Ron will cover the impact of different timing architectures.
