LMX2487 High Performance Delta-Sigma Low Power Dual PLLatinum Frequency Synthesizers

The LMX2487 is a low power, high performance delta-sigma fractional-N PLL with an auxiliary integer-N PLL. It 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 b.
