LMX2335L/LMX2336L

™

PLLatinum Low Power Dual Frequency Synthesizer for

RF Personal Communications

LMX2335L

1.1 GHz/1.1 GHz

Features

LMX2336L

2.0 GHz/1.1 GHz

n Ultra low current consumption

n 2.7V to 5.5V operation

General Description

n Selectable synchronous and asynchronous powerdown

mode:

The LMX2335L and LMX2336L are monolithic, integrated

dual frequency synthesizers, including two high frequency

prescalers, and are designed for applications requiring two

RF phase-lock loops. They are fabricated using National’s

0.5µ ABiC V silicon BiCMOS process.

I_CC1 µA (typ)

n Dual modulus prescaler: 64/65 or 128/129

n Selectable charge pump TRI-STATE^®mode

n Selectable charge pump current levels

The LMX2335L/36L contains two dual modulus prescalers. A

64/65 or a 128/129 prescaler can be selected for each RF

synthesizer. A second reference divider chain is included in

the IC for improved system noise. The LMX2335L/36L com-

bined with a high quality reference oscillator, two loop filters,

and two external voltage controlled oscillators generates

very stable low noise RF local oscillator signals.

™

n Selectable Fastlock mode

n Upgrade and compatible to LMX2335/36

n Small-outline, plastic, surface mount TSSOP package

n LMX2336 available in CSP package

Applications

n Cellular telephone systems (AMPS, ETACS, RCR-27)

n Cordless telephone systems

(DECT, ISM , PHS, CT-1+)

n Personal Communication Systems

(DCS-1800, PCN-1900)

n Dual Mode PCS phones

n Cable TV Tuners (CATV)

n Other wireless communication systems

Serial data is transferred into the LMX2335L/36L via a three

wire interface (Data, Enable, Clock). Supply voltage can

range from 2.7V to 5.5V. The LMX2335L/36L feature very

low current consumption; LMX2335L 4.0 mA at 5V,

LMX2336L 5.5 mA at 5V. The LMX2335L is available in SO,

TSSOP and CSP 16-pin surface mount plastic packages.

The LMX2336L is available in a TSSOP 20-pin and CSP

24-pin surface mount plastic package.
