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.
LMX2485Q-Q1 Features
* 1 Quadruple Modulus Prescaler for Lower Divides
* RF PLL: 8/9/12/13 or 16/17/20/21
* IF PLL: 8/9 or 16/17
* Advanced Delta Sigma Fractional Compensation
* 12-Bit or 22-Bit Selectable Fractional Modulus
* Up to 4th Order Programmable Delta-Sigma Modula
