LMX1501A/LMX1511 PLLatinum^TM

1.1 GHz Frequency Synthesizer

for RF Personal Communications

General Description

Features

RF operation up to 1.1 GHz

The LMX1501A and the LMX1511 are high performance fre-

quency synthesizers with integrated prescalers designed for

RF operation up to 1.1 GHz. They are fabricated using Na-

tional’s ABiC IV BiCMOS process.

2.7V to 5.5V operation

Low current consumption:

Dual modulus prescaler: 64/65 or 128/129

6 mA (typ) at V

The LMX1501A and the LMX1511 contain dual modulus

prescalers which can select either a 64/65 or a 128/129

divide ratio at input frequencies of up to 1.1 GHz. Using a

proprietary digital phase locked loop technique, the

LMX1501A/11’s linear phase detector characteristics can

generate very stable, low noise local oscillator signals.

Internal balanced, low leakage charge pump

Small-outline, plastic, surface mount JEDEC, 0.150

wide, (1501A) or TSSOP, 0.173 wide, (1511) package

Applications

Serial data is transferred into the LMX1501A and the

LMX1511 via a three line MICROWIRE^TMinterface (Data,

Enable, Clock). Supply voltage can range from 2.7V to 5.5V.

The LMX1501A and the LMX1511 feature very low current

consumption, typically 6 mA at 3V.

Cellular telephone systems

(AMPS, NMT, ETACS)

Portable wireless communications

(PCS/PCN, Cordless)

Advanced cordless telephone systems

The LMX1501A is available in a JEDEC 16-pin surface

mount plastic package. The LMX1511 is available in a

TSSOP 20-pin surface mount plastic package.
