Overview

LMX2487E High Performance Delta-Sigma Low Power Dual PLLatinum Frequency Synthesizer May 2007 LMX2487E 7.
5 GHz High Performance Delta-Sigma Low Power Dual PLLatinum™ Frequency Synthesizers with 3.
0 GHz Integer PLL General Description The LMX2487E 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 bandwidth.
The ability to push close in spur and phase noise energy to higher frequencies is a direct function of the modulator order.
Unlike analog compensation, t...
