PLLatinum Ultra Low Power Dual Frequency

Synthesizer for RF Personal Communications

LMX2330U 2.5 GHz/600 MHz

LMX2331U 2.0 GHz/600 MHz

LMX2332U 1.2 GHz/600 MHz

General Description

Features

n Ultra Low Current Consumption

n Upgrade and Compatible to LMX233xL Family

n 2.7V to 5.5V Operation

n Selectable Synchronous or Asynchronous Powerdown

Mode:

The LMX233xU devices are high performance frequency

synthesizers with integrated dual modulus prescalers. The

LMX233xU devices are designed for use as RF and IF local

oscillators for dual conversion radio transceivers.

A 32/33 or a 64/65 prescale ratio can be selected for the 2.5

GHz LMX2330U RF synthesizer. A 64/65 or a 128/129 pres-

cale ratio can be selected for both the LMX2331U and

LMX2332U RF synthesizers. The IF circuitry contains an 8/9

or a 16/17 prescaler. Using a proprietary digital phase locked

loop technique, the LMX233xU devices generate very

stable, low noise control signals for RF and IF voltage con-

trolled oscillators. Both the RF and IF synthesizers include a

two-level programmable charge pump. The RF synthesizer

has dedicated Fastlock circuitry.

I_CC-PWDN= 1 µA typical

n Selectable Dual Modulus Prescaler:

LMX2330U

LMX2331U

LMX2332U

RF: 32/33 or 64/65

RF: 64/65 or 128/129

LMX2330U/31U/32U IF: 8/9 or 16/17

n Selectable Charge Pump TRI-STATE^®Mode

n Programmable Charge Pump Current Levels

RF and IF: 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 LMX233xU family features ultra low

current consumption:

n Selectable Fastlock Mode for the RF Synthesizer

n Push-Pull Analog Lock Detect Output

n Available in 20-Pin TSSOP and 24-Pin Chip Scale

Package (CSP)

LMX2330U (2.5 GHz)—3.3 mA, LMX2331U (2.0 GHz)

—2.9 mA, LMX2332U (1.2 GHz)—2.5 mA at 3.0V.

Applications

The LMX233xU devices are available in 20-Pin TSSOP and

24-Pin CSP surface mount plastic packages.
