FEATURES  
DESCRIPTION  
The LMX233XL family of monolithic, integrated dual  
frequency synthesizers, including prescalers, is to be  
used as a local oscillator for RF and first IF of a dual  
conversion transceiver. It is fabricated using TI's 0.5μ  
ABiC V silicon BiCMOS process.

The LMX233XL contains dual modulus prescalers. A  
64/65 or a 128/129 prescaler (32/33 or 64/65 in the  
2.5 GHz LMX2330L) can be selected for the RF  
synthesizer and a 8/9 or a 16/17 prescaler can be  
selected for the IF synthesizer. LMX233XL, which  
employs a digital phase locked loop technique,  
combined with a high quality reference oscillator,  
provides the tuning voltages for voltage controlled  
oscillators to generate very stable, low noise signals  
for RF and IF local oscillators. Serial data is  
transferred into the LMX233XL via a three wire  
interface (Data, Enable, Clock). Supply voltage can  
range from 2.7V to 5.5V. The LMX233XL family  
features very low current consumption;
