DESCRIPTION  
The LMX2487 is a low power, high performance  
delta-sigma fractional-N PLL with an auxiliary integer-  
N PLL. It is fabricated using TI’s advanced process.

12 Bit or 22 Bit Selectable Fractional  
Modulus  
–
Up to 4th Order Programmable Delta-Sigma  
Modulator  
With delta-sigma architecture, fractional spurs at  
lower offset frequencies are pushed to higher  
frequencies outside the loop bandwidth. The ability to  
push close in spur and phase noise energy to higher  
frequencies is a direct function of the modulator  
order. Unlike analog compensation, the digital  
feedback technique used in the LMX2487 is highly  
resistant to changes in temperature and variations in  
wafer processing. The LMX2487 delta-sigma  
modulator is programmable up to fourth order, which  
allows the designer to select the optimum modulator  
order to fit the phase noise, spur, and lock time  
requirements of the system.

Digital Lock Detect Output  
Serial data for programming the LMX2487 is  
transferred via a three line high speed (20 MHz)  
MICROWIRE interface. The LMX2487 offers fine  
frequency resolution, low spurs, fast programming  
speed, and a single word write to change the  
frequency. This makes it ideal for direct digital  
modulation applications, where the N counter is  
directly modulated with information. The LMX2487 is  
available in a 24 lead 4.0 X 4.0 X 0.8 mm WQFN  
package.
