LMX2315/LMX2320/LMX2325 PLLatinum^TM

Frequency Synthesizer

for RF Personal Communications

LMX2325 2.5 GHz

LMX2320 2.0 GHz

LMX2315 1.2 GHz

General Description

Features

RF operation up to 2.5 GHz

The LMX2315/2320/2325’s are high performance frequen-

cy synthesizers with integrated prescalers designed for RF

operation up to 2.5 GHz. They are fabricated using Nation-

al’s ABiC IV BiCMOS process.

2.7V to 5.5V operation

Low current consumption

Dual modulus prescaler:

LMX2325

LMX2320/LMX2315

A 64/65 or a 128/129 divide ratio can be selected for the

LMX2315 and LMX2320 RF synthesizer at input frequencies

of up to 1.2 GHz and 2.0 GHz, while 32/33 and 64/65 divide

ratios are available in the 2.5 GHz LMX2325. Using a propri-

etary digital phase locked loop technique, the LMX2315/

2320/2325’s linear phase detector characteristics can gen-

erate very stable, low noise signals for controlling a local

oscillator.

32/33 or 64/65

64/65 or 128/129

Internal balanced, low leakage charge pump

Power down feature for sleep mode:

30 mA (typ) at V

Small-outline, plastic, surface mount TSSOP, 0.173

wide

Serial data is transferred into the LMX2320 and the

LMX2325 via a three line MICROWIRE^TMinterface (Data,

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

The LMX2315, LMX2320 and the LMX2325 feature very low

current consumption, typically 6 mA, 10 mA and 11 mA re-

spectively.

Applications

Cellular telephone systems

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

Portable wireless communications (DECT, PHS)

CATV

Other wireless communication systems

The LMX2315, LMX2320 and the LMX2325 are available in

a TSSOP 20-pin surface mount plastic package.
