General Description

The LMX2582 device is a low-noise, wideband RF PLL with integrated VCO that supports a frequency range from 20 MHz to 5.5 GHz.

The device supports both fractional-N and integer-N modes, with a 32-bit fractional divider allowing fine frequency selection.

Integrated noise of 47 fs for 1.8-GHz output makes it an ideal low-noise source.
