PLLatinum Ultra Low Power Frequency Synthesizer for

RF Personal Communications

LMX2310U 2.5 GHz

LMX2312U 1.2 GHz

General Description

The LMX2310/1/2/3U are high performance frequency syn-

thesizers. The LMX2310/1/2U use a selectable, dual modu-

lus 32/33 and 16/17 prescaler. The LMX2313U uses a se-

lectable, dual modulus 16/17 and 8/9 prescaler. The device,

when combined with a high quality reference oscillator and a

voltage controlled oscillator, generates very stable, low noise

local oscillator signals for up and down conversion in wire-

less communication devices.

LMX2311U 2.0 GHz

LMX2313U 600 MHz

Features

n RF operation up to 2.5 GHz

n 2.7V to 5.5V operation

n Ultra Low Current Consumption

n Low prescaler values

LMX2310/1/2U 32/33 or 16/17

LMX2313U 16/17 or 8/9

n Excellent Phase Noise

n Internal balanced, low leakage charge pump

n Selectable Charge Pump Current Levels

n Selectable Fastlock mode with Time-Out Counter

n Low Voltage MICROWIRE interface (1.72V to V_CC

n Digital and Analog Lock Detect

n Small 20-pad Thin Chip Scale Package

Serial data is transferred into LMX2310/1/2/3U via a three-

wire interface (Data, Enable, Clock) that can be directly

interfaced with low voltage baseband processors. Supply

voltage can range from 2.7V to 5.5V. LMX2310U features

very low current consumption, typically 2.3 mA at 3.0V.

)

The LMX2310/1/2/3U are manufactured using National’s

0.5µ ABiC V silicon BiCMOS process and is available in

20-pin CSP packages.

Applications

n Cellular DCS, PCS, WCDMA telephone systems

n Wireless Local Area Networks (WLAN)

n Global Positioning Systems (GPS)

n Other wireless communications systems
