描述
The 843201-375 is a low phase-noise frequency margining synthesizer. In the default mode, the device nominally generates a 375MHz LVPECL output clock signal from a 25MHz crystal input. There is also a frequency margining mode available where the device can be configured, using control pins, to vary the output frequency up or down from nominal by 5%. The 843201-375 is provided in a 16-pin TSSOP package.
特性
