Texas Instruments LMX1214 RF Buffer & Divider
Texas Instruments LMX1214 RF Buffer and Divider 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 Texas Instruments LMX1214 supports both buffer and divide modes for high-frequency clocks. This device can distribute the multichannel, low skew, ultra-low noise local oscillator signals to multiple mixers.
