LMX2487 Datasheet (Texas Instruments) - Frequency Synthesizers

LMX2487, Frequency Synthesizers

The LMX2487 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.
