Overview
Features n LTC6948 Ultralow Noise 0.
37GHz to 6.
39GHz Fractional-N Synthesizer with Integrated VCO Description The LTC®6948 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.
The programmable VCO output divider, with a range of 1 through 6, extends the output frequency range.
