The FS100 ultra-low noise frequency synthesizer can be used with state-of-the-art crystal frequency sources without degrading phase noise or environmental stability. The FS100 multiplies the input frequency of 10 MHz and provides a 100 MHz output, while maintaining spurious signal levels below -55 dBc. The FS100 is ideal for phase locking 100 MHz crystal sources with 10 MHz references. Other multiplied frequency outputs are available.
