PLLatinum Dual High Frequency Synthesizer for RF  
Personal Communications  
LMX2430 3.0 GHz/0.8 GHz  
LMX2433 3.6 GHz/1.7 GHz  
LMX2434 5.0 GHz/2.5 GHz  
General Description  
Features  
n Low Current Consumption  
n 2.25V to 2.75V Operation  
The LMX243x devices are high performance frequency syn-  
thesizers with integrated dual modulus prescalers. The  
LMX243x devices are designed for use as RF and IF local  
oscillators for dual conversion radio transceivers.  
n Selectable Synchronous or Asynchronous Powerdown  
Mode  
A 32/33 or a 16/17 prescale ratio can be selected for the 5.0  
GHz LMX2434 RF synthesizer. An 8/9 or a 16/17 prescale  
ratio can be selected for both the LMX2430 and LMX2433  
RF synthesizers. The IF circuitry contains an 8/9 or a 16/17  
prescaler. Using a proprietary digital phase locked loop tech-  
nique, the LMX243x devices generate very stable, low noise  
control signals for RF and IF voltage controlled oscillators.  
Both the RF and IF synthesizers include a two-level pro-  
grammable charge pump. Both the RF and IF synthesizers  
have dedicated Fastlock circuitry with integrated timeout  
counters. Furthermore, only a single word write is required to  
power up and tune the synthesizers to a new frequency.

n Fastlock Technology with Integrated Timeout Counters  
n Digital Filtered Lock Detect Output  
n Analog Lock Detect Output (supports both Push-Pull  
and Open Drain configurations)  
n 1.8V MICROWIRE Logic Interface  
n Available in 20-Pin TSSOP and 20-Pin UTCSP  
Serial data is transferred to the devices via a three-wire  
interface (DATA, LE, CLK). A low voltage logic interface  
allows direct connection to 1.8V devices. Supply voltages  
from 2.25V to 2.75V are supported . The LMX243x family  
features low current consumption:  
Applications  
n Mobile Handsets  
(GSM, GPRS, W-CDMA, CDMA, PCS, AMPS, PDC,  
DCS)  
LMX2430 (3.0 GHz/ 0.8 GHz)—2.8 mA/ 1.4 mA, LMX2433  
(3.6 GHz/ 1.7 GHz) —3.2 mA/ 2.0 mA, LMX2434 (5.0 GHz/  
2.5 GHz)—4.6 mA/ 2.4 mA at 2.50V.  
n Cordless Handsets  
(DECT, DCT)  
n Wireless Data  
The LMX243x devices are available in 20-Pin TSSOP and  
20-Pin UTCSP surface mount plastic packages.  
n Cable TV Tuners  
Thin Shrink Small Outline Package (MTC20)  
Ultra Thin Chip Scale Package (SLE20A)
