.. LMX2485/LMX2485E High Performance Delta-Sigma Low Power Dual PLLatinum Frequency Synthesizer February 2006 LMX2485/LMX2485E 50 MHz - 3.0 GHz High Performance Delta-Sigma Low Power Dual PLLatinum™ Frequency Synthesizers with 800 MHz Integer PLL General Description The LMX2485 is a low power, high performance delta-sigma fractional-N PLL with an auxiliary integer-N PLL. The device is fabricated using National Semiconductor’s advanced process. With delta-sigma architecture, fractional spurs at lower offset frequencies are pushed to higher frequencies outside the loop bandwidth. The ability to push close in spur and phase noise energy to higher frequencies is a direct...
