DESCRIPTION  
Integrated Loop Filter  
LMX2515 is a highly integrated, high performance,  
low power frequency synthesizer system optimized  
for Japan PDC mobile handsets. Using a proprietary  
digital phase locked loop technique, LMX2515  
generates very stable, low noise local oscillator  
signals for up and down conversion in wireless  
communications devices.  
Low Spurious, Low Phase Noise Fractional-  
N RF PLL Based on 10-Bit Delta Sigma  
Modulator  
–
Frequency Resolution Down to 20 kHz  
•
Supports Various Reference Frequencies  
12.6/14.4/25.2/26.0 MHz  
–
LMX2515 includes a voltage controlled oscillator  
(VCO), a loop filter, and a fractional-N RF PLL based  
on a delta sigma modulator. In concert these blocks  
form a closed loop RF synthesizer system. The  
LMX2515LQ0701 supports the Japan PDC800 band  
and the LMX2515LQ1321 supports Japan PDC1500  
band.

Digital Filtered Lock Detect Output  
Hardware and Software Power Down Control  
Serial data is transferred to the device via a three-  
wire MICROWIRE interface (DATA, LE, CLK).  
Operating supply voltage ranges from 2.5 V to 3.3 V.  
LMX2515 features low current consumption.  
LMX2515 is available in a 28-pin WQFN package.
