General Description  
The LMX1600/01/02 is part of a family of monolithic inte-  
grated dual frequency synthesizers designed to be used in a  
local oscillator subsystem for a radio transceiver. It is fabri-  
cated using National’s 0.5u ABiC V silicon BiCMOS process.  
Features  
n VCC = 2.7V to 3.6V operation  
n Low current consumption:  
@
4 mA 3V (typ) for LMX1601  
@
5 mA 3V (typ) for LMX1600 or LMX1602  
n PLL Powerdown mode: ICC = 1 µA typical  
n Digital Filtered Lock Detects  
n Dual modulus prescaler:  
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  
— 2 GHz/500 MHz option:  
(Main) 32/33 (Aux) 8/9  
— 1.1 GHz/500 MHz option: (Main) 16/17 (Aux) 8/9  
is transferred into the LMX1600/01/02 via a MICROWIRE  
serial interface (Data, Clock, LE).  
— 1.1 GHz/1.1 GHz option:  
(Main) 16/17 (Aux) 16/17  
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.  
Applications  
n Cordless / Cellular / PCS phones  
n Other digital mobile phones  
The LMX1600/01/02 is available in a 16 pin TSSOP surface  
mount plastic package.
