The LMX1214 features high output frequency, ultra-low noise floor, and very low skew clocks distribution. The device has four high-frequency output clocks and a lower frequency auxiliary clock output. The device supports both buffer and divide mode for the high-frequency clocks. This device can distribute the mutlichannel, low skew, ultra-low noise local oscillator signals to multiple mixers.
