Package: QFN 28 Pin Type

Manufacturer: Analog Device, Linear Technology


LTC6948 datasheet



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.


1. Low Noise Fractional-N PLL with Integrated VCO
