LMX2485Q-Q1 - High Performance Delta-Sigma Low Power Dual PLLatinum Frequency Synthesizers
The LMX2485Q-Q1 is a low power, high performance delta-sigma fractional-N PLL with an auxiliary integerN PLL.
The device 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.
