LMX2487E - Frequency Synthesizers
The LMX2487E device is a low power, high performance delta-sigma fractional-N PLL with an auxiliary integer-N PLL.
It is fabricated using TI’s advanced process.
With delta-sigma architecture, fractional spurs at lower offset frequencies are pushed to higher frequencies outside the loop bandwidth.
