LMX2314/LMX2315 PLLatinum^TM

1.2 GHz Frequency Synthesizer

for RF Personal Communications

General Description

Features

RF operation up to 1.2 GHz

The LMX2314 and the LMX2315 are high performance fre-

quency synthesizers with integrated prescalers designed for

RF operation up to 1.2 GHz. They are fabricated using Na-

tional’s ABiC IV BiCMOS process.

2.7V to 5.5V operation

Low current consumption:

6 mA (typ) at V

The LMX2314 and the LMX2315 contain dual modulus pre-

scalers which can select either a 64/65 or a 128/129 divide

ratio at input frequencies of up to 1.2 GHz. Using a proprie-

tary digital phase locked loop technique, the LMX2314/15’s

linear phase detector characteristics can generate very sta-

ble, low noise local oscillator signals.

Dual modulus prescaler: 64/65 or 128/129

Internal balanced, low leakage charge pump

Power down feature for sleep mode:

Small-outline, plastic, surface mount JEDEC, 0.150

30 mA (typ) at V

wide, (2314) or TSSOP, 0.173 wide, (2315) package

Serial data is transferred into the LMX2314 and the

LMX2315 via a three line MICROWIRE^TMinterface (Data,

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

The LMX2314 and the LMX2315 feature very low current

consumption, typically 6 mA at 3V.

Applications

Cellular telephone systems

(GSM, IS-54, IS-95, RCR-27)

Portable wireless communications

(DECT, ISM902-928 CT-2)

The LMX2314 is available in a JEDEC 16-pin surface mount

plastic package. The LMX2315 is available in a TSSOP

20-pin surface mount plastic package.
