Texas Instruments LMX2592 Wideband Frequency Synthesizer
Texas Instruments LMX2592 Wideband Frequency Synthesizer is a low-noise, wideband RF PLL with an integrated VCO. The integrated VCO supports a frequency range from 20MHz to 9.8GHz. The device supports both fractional-N and integer-N modes, with a 32-bit fractional divider allowing fine frequency selection. Integrated noise of 49fs for 6GHz output makes it an ideal low noise source. Combining best-in-class PLL and integrated VCO noise with integrated LDOs, this device removes the need for multiple discrete devices in high-performance systems.Features
