LMX2582 Wideband PLLatinum RF Synthesiser

Texas Instruments LMX2582 Wideband PLLatinum RF Synthesiser is a low-noise, wideband RF PLL with integrated VCO that supports a frequency range from 20MHz to 5.5GHz. The device supports both fractional-N and integer-N modes, with a 32-bit fractional divider allowing fine frequency selection. Integrated noise of 47fs for 1.8GHz 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. The device accepts input frequencies up to 1.4GHz, which combined with frequency dividers and programmable low-noise multiplier allows flexible frequency planning. The additional programmable low-noise multiplier lets users mitigate the impact of integer boundary spurs. In fractional-N mode, the device can adjust the output phase by a 32-bit resolution.
