PLLatinum Ultra Low Power Dual Frequency  
Synthesizer for RF Personal Communications  
LMX2335U  
LMX2336U  
1.2 GHz/1.2 GHz  
2.0 GHz/1.2 GHz  
General Description  
Features  
n Ultra Low Current Consumption  
n Upgrade and Compatible to the LMX2335L and  
LMX2336L devices  
n 2.7V to 5.5V operation  
n Selectable Synchronous or Asynchronous Powerdown  
Mode:  
The LMX2335U and LMX2336U devices are high perfor-  
mance frequency synthesizers with integrated dual modulus  
prescalers. The LMX2335U and LMX2336U devices are  
designed for use in applications requiring two RF  
phase-locked loops.  
A 64/65 or a 128/129 prescale ratio can be selected for each  
RF synthesizer. Using a proprietary digital phase locked loop  
technique, the LMX2335U and LMX2336U devices generate  
very stable, low noise control signals for the RF voltage  
ICC-PWDN = 1 µA typical at 3.0V  
n Selectable Dual Modulus Prescaler  
RF1: 64/65 or 128/129  
controlled oscillators. Both RF synthesizers include  
a
RF2: 64/65 or 128/129  
two-level programmable charge pump. The RF1 synthesizer  
has dedicated Fastlock circuitry.  
n Selectable Charge Pump TRI-STATE® Mode  
n Programmable Charge Pump Current Levels  
RF1 and RF2: 0.95 or 3.8 mA  
Serial data is transferred to the devices via a three wire  
interface (Data, LE, Clock). Supply voltages from 2.7V to  
5.5V are supported. The LMX2335U and the LMX2336U  
feature very low current consumption:  
™
n Selectable Fastlock Mode for the RF1 Synthesizer  
n Push-Pull Analog Lock Detect Mode  
n LMX2335U is available in 16-Pin TSSOP and 16-Pin  
CSP  
n LMX2336U is available in 20-Pin TSSOP, 24-Pin CSP,  
and 20-Pin UTCSP  
LMX2335U (1.2 GHz)– 3.0 mA, LMX2336U (2.0 GHz)–  
3.5 mA at 3.0V.  
The LMX2335U device is available in 16-pin TSSOP, and  
16-pin Chip Scale Package (CSP) surface mount plastic  
packages. The LMX2336U device is available in 20-Pin  
TSSOP, 24-Pin CSP, and 20-Pin UTCSP surface mount  
plastic packages.  
Applications  
n Mobile Handsets  
(GSM, GPRS, W-CDMA, CDMA, PCS, AMPS, PDC,  
DCS)  
n Cordless Handsets (DECT, DCT)  
n Wireless Data  
n Cable TV Tuners
