LMX2335U/LMX2336U

™

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

I_CC-PWDN= 1 µA typical at 3.0V

n Selectable Dual Modulus Prescaler

RF1: 64/65 or 128/129

controlled oscillators. Both RF synthesizers include

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
