LMX2592 - Texas Instruments

LMX2592 RF Synthesizer

The LMX2592 device is a low-noise, wideband RF PLL with integrated VCO that supports a frequency range from 20 MHz to 9.8 GHz. The device supports both fractional-N and integer-N modes, with a 32-bit fractional divider allowing fine frequency selection. Integrated noise of 49 fs for 6-GHz output makes it an ideal low-noise source. Combining best-in-class PLL.
