LMX2485E - High Performance Delta-Sigma Low Power Dual PLLatinum Frequency Synthesizers
The LMX2485 is a low power, high performance delta-sigma fractional-N PLL with an auxiliary integer-N PLL.
The device is fabricated using National Semiconductor’s advanced process.
With delta-sigma architecture, fractional spurs at lower offset frequencies are pushed to higher frequencies outside th
