General Description

The LMX2335, LMX2336 and LMX2337 are monolithic, inte-

grated dual frequency synthesizers, including two high fre-

quency prescalers, and are designed for applications requir-

ing two RF phase-lock loops. They are fabricated using

National’s ABiC IV 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 LMX2335/36/37 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. LMX2335/36/37, which

employ a digital phase locked loop technique, combined with

a high quality reference oscillator and loop filters, provide the

tuning voltages for voltage controlled oscillators to generate

very stable low noise RF local oscillator signals.

™

n Selectable FastLock mode

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)

Serial data is transferred into the LMX2335/36/37 via a three

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

range from 2.7V to 5.5V. The LMX2335/36/37 feature very

low current consumption; LMX2335/37 −10 mA at 3V,

LMX2336 −13 mA at 3V. The LMX2335/37 are available in

n Dual Mode PCS phones

n CATV

n Other wireless communication systems
