FEATURES  
DESCRIPTION  
The LMX1600/01/02 is part of a family of monolithic  
integrated dual frequency synthesizers designed to  
be used in a local oscillator subsystem for a radio  
transceiver. It is fabricated using TI's 0.5u ABiC V  
silicon BiCMOS process.  
23  
VCC = 2.7V to 3.6V Operation  
Low Current Consumption:  
4 mA @ 3V (Typ) for LMX1601  
5 mA @ 3V (Typ) for LMX1600 or LMX1602  
PLL Powerdown Mode: ICC = 1 µA Typical  
Digital Filtered Lock Detects  
The LMX1600/01/02 contains two dual modulus  
prescalers, four programmable counters, two phase  
detectors and two selectable gain charge pumps  
necessary to provide the control voltage for two  
external loop filters and VCO loops. Digital filtered  
lock detects for both PLLs are included. Data is

VCC supply voltage can range from 2.7V to 3.6V. The  
LMX1600/01/02 features very low current  
consumption - typically 4.0 mA at 3V for LMX1601,  
5.0 mA at 3V for LMX1600 or LMX1602. Powerdown  
for the PLL is hardware controlled.  
1.1 GHz/1.1 GHz Option: (Main) 16/17 (Aux)

APPLICATIONS  
Cordless / Cellular / PCS Phones  
Other Digital Mobile Phones  
The LMX1600/01/02 is available in a 16 pin TSSOP  
surface mount plastic package.
