Part Number : LTC6948
Function : Ultralow Noise 0.37GHz to 6.39GHz Fractional-N Synthesizer with Integrated VCO
Package : UFD 28 Pin type
Maker : Linear Technology
The LTC6948 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), ultralow noise charge pump, fractional feedback divider, and VCO output divider.
The fractional divider uses an advanced, 4th order Δ∑ modulator which provides exceptionally low spurious levels. This allows wide loop bandwidths, producing extremely low integrated phase noise values.
