LMX2485 Datasheet (Texas Instruments) - 3-GHz Delta-Sigma Low-Power Dual PLLatinum Frequency Synthesizer

LMX2485, 3-GHz Delta-Sigma Low-Power Dual PLLatinum Frequency Synthesizer

The LMX2485 device is a low power, high performance delta-sigma fractional-N PLL with an auxiliary integer-N PLL.

The device is fabricated using Texas Instruments' advanced process.

With delta-sigma architecture, fractional spurs at lower offset frequencies are pushed to higher frequencies outside t
