LMX2324A

PLLatinum™ 2.2 GHz Frequency Synthesizer for RF

Personal Communications (SL163188)

General Description

Features

The LMX2324A is a high performance frequency synthesizer

with integrated 32/33 dual modulus prescaler designed for RF

operation up to 2.2 GHz. Using a proprietary digital phase

locked loop technique, the LMX2324A's linear phase detector

characteristics can generate very stable, low noise control

signals for UHF and VHF voltage controlled oscillators.

RF operation up to 2.2 GHz

■

2.7V to 5.5V operation

Low current consumption: I_CC= 3.5 mA (typ) at V_CC= 3.0V

Dual modulus prescaler: 32/33

■

Internal balanced, low leakage charge pump

Serial data is transferred into the LMX2324A via a three-line

MICROWIRE™ interface (Data, LE, Clock). Supply voltage

range is from 2.7V to 5.5V. The LMX2324A features very low

current consumption, typically 3.5 mA at 3V. The charge

pump provides 4 mA output current.

Applications

Cellular telephone systems (GSM, NADC, CDMA, PDC)

■

Personal wireless communications (DCS-1800, DECT,

CT-1+)

The LMX2324A is manufactured using National's ABiC V

BiCMOS process and is packaged in a 16-pin TSSOP and a

16-pin Chip Scale Package (CSP).

Wireless local area networks (WLANs)

■

Other wireless communication systems
