LMX2485Q-Q1 Description
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.
