8V49NS0412

FemtoClock® NG Clock Generator with Four Dividers 8V49NS0412 Datasheet Description The 8V49NS0412 is a clock generator with four output dividers: three integers, and one that is either integer or fractional. When used with an external crystal, the 8V49NS0412 generates high-performance timing for the communications and datacom markets, especially for applications that demand extremely low phase noise, such as 10GE, 40GE, 100G, and 400GE. The 8V49NS0412 provides versatile frequency configurations and output formats, and is optimized to deliver excellent phase noise performance. The device delivers an optimum combination of high clock frequency and low phase noise performance, combined with high power supply noise rejection. The 8V49NS0412 supports two types of output levels: LVPECL or LVDS on eleven of its outputs. In addition, the device has a single LVCMOS output that can provide a generated clock, or act as a reference bypass output. The device can be configured to deliver specific...
