LTC6951IUHF-1#PBF

LTC6951 is an ultralow jitter multioutput clock synthesizer with integrated VCO. It is a high performance, low noise, phase locked loop (PLL) with a fully integrated VCO. The low noise VCO uses no external components and is internally calibrated to the correct output frequency with no external system support. The clock generation section provides five outputs based on the VCO prescaler signal with individual dividers for each output. Four outputs feature very low noise, low skew CML logic. The fifth output is low noise LVDS. All outputs can be synchronized and set to precise phase alignment using the programmable delays. Application includes high performance data converter clocking, wireless infrastructure, test and measurement.
