PLLatinum 2.0 GHz Frequency Synthesizer for RF

Personal Communications

General Description

Features

n RF operation up to 2.0 GHz

n 2.7V to 5.5V operation

The LMX2323 is a high performance frequency synthesizer

with integrated 32/33 dual modulus prescaler designed for

RF operation up to 2.0 GHz. Using a proprietary digital

phase locked loop technique, the LMX2323’s linear phase

detector characteristics can generate very stable, low noise

control signals for UHF and VHF voltage controlled oscilla-

tors.

n Low current consumption: Icc = 3.5mA (typ) at

Vcc=3.0V

n Digital Lock Detect

n Dual modulus prescaler: 32/33

n Internal balanced, low leakage charge pump

Serial data is transferred into the LMX2323 via a three-line

™

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

Applications

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

PHS)

range is from 2.7V to 5.5V. The LMX2323 features very low

curent consumption, typically 3.5mA at 3V. The charge pump

provides 4 mA output current.

n Personal wireless communications (DCS-1800, DECT,

CT-1+)

The LMX2323 is manufactured using National’s ABiC V

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

n Wireless local area networks (WLANs)

n DCS/PCS infrastructure equipment

n Other wireless communication systems
