LMX2582 Wideband PLLatinum RF Synthesizer

Texas Instruments LMX2582 Wideband PLLatinum RF Synthesizer 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.
