LMX2332U 1.2 GHz/600 MHz  
General Description  
Features  
n Ultra Low Current Consumption  
The LMX233xU devices are high performance frequency  
synthesizers with integrated dual modulus prescalers. The  
LMX233xU devices are designed for use as RF and IF local  
oscillators for dual conversion radio transceivers.  
n Upgrade and Compatible to LMX233xL Family  
n 2.7V to 5.5V Operation  
n Selectable Synchronous or Asynchronous Powerdown  
Mode:  
ICC-PWDN = 1 µA typical  
n Selectable Dual Modulus Prescaler:  
A 32/33 or a 64/65 prescale ratio can be selected for the 2.5  
GHz LMX2330U RF synthesizer. A 64/65 or a 128/129 pres-  
cale ratio can be selected for both the LMX2331U and  
LMX2332U RF synthesizers. The IF circuitry contains an 8/9  
or a 16/17 prescaler. Using a proprietary digital phase locked  
loop technique, the LMX233xU devices generate very  
stable, low noise control signals for RF and IF voltage con-  
trolled oscillators. Both the RF and IF synthesizers include a  
two-level programmable charge pump. The RF synthesizer  
has dedicated Fastlock circuitry.

n Selectable Charge Pump TRI-STATE® Mode  
n Programmable Charge Pump Current Levels  
RF and IF: 0.95 or 3.8 mA  
Serial data is transferred to the devices via a three-wire  
interface (Data, LE, Clock). Supply voltages from 2.7V to  
5.5V are supported. The LMX233xU family features ultra low  
current consumption:
