Part Details:

LMX1600/LMX1601/LMX1602 June 2005 LMX1600 2.0 GHz/500 MHz LMX1601 1.1 GHz/500 MHz LMX1602 1.1 GHz/1.1 GHz PLLatinumTM Low Cost Dual Frequency SynthesizerGeneral Description Features The LMX1600/01/02 is part of a family of monolithic inte- n V = 2.7V to 3.6V operation CC grated dual frequency synthesizers designed to be used in a n Low current consumption: local oscillator subsystem for a radio transceiver. It is fabri- 4 mA @ 3V (typ) for LMX1601 cated using National s 0.5u ABiC V silicon BiCMOS process. 5 mA @ 3V (typ) for LMX1600 or LMX1602 PLLatinum The LMX1600/01/02 contains two dual modulus prescalers, n PLL Powerdown mode: I = 1 µA typical CC four programmable counters, two phase detectors and two n Digital Filtered Lock Detects selectable gain charge pumps necessary to provide the n Dual modulus prescaler: control voltage for two external loop filters and VCO loops. -- 2 GHz/500 MHz option: (Main) 32/33 (Aux) 8/9 Digital filtered lock detects for both PLLs are included. Data -- 1.1 GHz/500 MHz option: (Main) 16/17 (Aux) 8/9 is transferred into the LMX1600/01/02 via a MICROWIRETM -- 1.1 GHz/1.1 GHz option: (Main) 16/17 (Aux) 16/17 serial interface (Data, Clock, LE). V supply voltage can range from 2.7V to 3.6V. The CC Applications Low LMX1600/01/02 features very low current consumption - n Cordless / Cellular / PCS phones typically 4.0 mA at 3V for LMX1601, 5.0 mA at 3V for n Other digital mobile phones LMX1600 or LMX1602. Powerdown for the PLL is hardware Cost controlled. The LMX1600/01/02 is available in a 16 pin TSSOP surfacemount plastic package. Dual Functional Block Diagram Frequency
