9DML4493ANLGI

9DML4493ANLGI is a 4:4 clock MUX for PCI express gen1–6. It can also operate as a dual 2-input, 2-output clock multiplexer. It has very low additive phase jitter and is suitable for all PCIe data rates. The device supports today's complex system power sequencing requirements with power down tolerant and flexible power sequencing features. Typical application includes servers storage, networking, high-performance computing, accelerators.
