9DML4493ANLGI8

9DML4493ANLGI8 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.

• 8fs RMS typical (PCIe Gen6 CC at 100MHz), 66fs RMS typical (12KHz–20MHz at 156.25M)
• Supports common clocked (CC) and IR (SRIS, SRNS) timing architectures
• Propagation delay 1.2ns typical
• Four differential inputs support LVPECL, LVDS, HCSL or LVCMOS reference clocks
• FPS ensures good behaviour on powered up w/o input clock or when input clock is present w/o power
• PDT inputs: CLK-SEL-tri, OE pins, IOA-tri, IOB-tri, ZOUTSEL driven when 9DML4493 is not powered up
• Accepts input frequencies ranging from 1PPS (1Hz) to 350MHz
• Configured via pin straps - no serial bus needed
• Glitch-free output enable pins for each output, spread-spectrum tolerant
• 32-VFQFPN, temperature range from -40° to +85°C, voltage supply of 1.8V, 2.5V, or 3.3V
