FEATURES  
DESCRIPTION  
The LMX2370 monolithic, integrated dual frequency  
synthesizer, including prescalers, is designed to be  
used as a first and second local oscillator for dual  
mode or dual conversion transceivers. It is fabricated  
using TI's 0.5u ABiCV silicon BiCMOS process. The  
LMX2370 contains two dual modulus prescalers. A  
32/33 or a 16/17 prescaler can be selected for the  
Main synthesizer and a 16/17 or 8/9 prescaler can be  
selected for the Aux synthesizer. Using a digital  
phase locked loop technique, the LMX2370  
generates very stable, low noise control signals for  
UHF and VHF voltage controlled oscillators (VCOs).  
Serial data is transferred into the LMX2370 via a 1.8
