PLLatinum High Performance Frequency Synthesizer  
System with Integrated VCO  
General Description  
Features  
The LMX2531 is a low power, high performance frequency  
synthesizer system which includes a fully integrated delta-  
sigma PLL and VCO with fully integrated tank circuit. The  
third and fourth poles are also integrated and also adjust-  
able. Also included are integrated ultra-low noise and high  
precision LDOs for the PLL and VCO which give higher  
supply noise immunity and also more consistent perfor-  
mance. When combined with a high quality reference oscil-  
lator, the LMX2531 generates very stable, low noise local  
oscillator signals for up and down conversion in wireless  
communication devices. The LMX2531 is a monolithic inte-  
grated circuit, fabricated in an advanced BiCMOS process.  
There are actually several different versions of this product,  
for which the primary difference is frequency range.  
Multiple Frequency Options Available  
— See Selection Guide Below  
— Frequencies from: 765 MHz - 2790 MHz  
PLL Features  
— Fractional-N Delta Sigma Modulator Order  
programmable up to 4th order  
— FastLock/Cycle Slip Reduction with Timeout Counter  
— Partially integrated, adjustable Loop Filter  
— Very low phase noise and spurs  
VCO Features  
— Integrated tank inductor  
— Low phase noise  
Other Features  
— 2.8 V to 3.2 V Operation  
— Low Power-Down Current  
— 1.8V MICROWIRE Support  
— Package: 36 Lead LLP  
Device programming is facilitated using  
MICROWIRE Interface that can operate down to 1.8 volts.  
a three-wire  
Supply voltage range is 2.8 to 3.2 Volts. The LMX2531 is  
available in a 36 pin 6x6x0.8 mm Lead-Free Leadless Lead-  
frame Package (LLP).
