General DescriptionThe LMX1600/01/02is partofa familyof monolithic inte-
grated dual frequency synthesizers designedtobe usedina
local oscillator subsystemfora radio transceiver.Itis fabri-
cated using National’s 0.5uABiC Vsilicon BiCMOS process.
The LMX1600/01/02 containstwo dual modulus prescalers,
four programmable counters,two phase detectors andtwo
selectable gain charge pumps necessaryto provide thecon-
trol voltagefortwo external loop filtersand VCO loops. Digi-
tal filtered lock detectsfor both PLLsare included. Datais
transferred intothe LMX1600/01/02viaa MICROWIRE™
serial interface (Data, Clock, LE).
VCC supply voltage can range from 2.7Vto 3.6V. The
LMX1600/01/02 features very low current consumption-
typically4.0mAat3Vfor LMX1601,5.0 mAat3Vfor
LMX1600or LMX1602. Powerdownforthe PLLis hardware
controlled.
The LMX1600/01/02is availableina16 pinTSSOP surface
mount plastic package.
Features VCC= 2.7Vto 3.6V operation Low current consumption:
4mA@3V (typ)for LMX1601
5mA@3V (typ)for LMX1600or LMX1602 PLL Powerdown mode:ICC=1μA typical Dual modulus prescaler:2 GHz/500 MHz option: (Main) 32/33 (Aux)8/91.1 GHz/500 MHz option: (Main) 16/17 (Aux)8/91.1 GHz/1.1 GHz option: (Main) 16/17 (Aux) 16/17 Digital Filtered Lock Detects
Applications Cordless/ Cellular/ PCS phones Other digital mobile phones
