LTC6946IUFD-4#PBF

LINEAR TECHNOLOGY  LTC6946IUFD-4#PBF  芯片

The is a high performance low noise 6.39GHz Phase-locked Loop PLL with a fully integrated VCO, including a reference divider, phase-frequency detector PFD with phase-lock indicator, ultralow noise charge pump, integer feedback divider and VCO output divider. The charge pump contains selectable high and low voltage clamps useful for VCO monitoring. The integrated low noise VCO uses no external components. It is internally calibrated to the correct output frequency with no external system support. The part features a buffered, programmable VCO output divider with a range of 1 through 6, providing a wide frequency range.
