LMX2346/LMX2347

™

PLLatinum Frequency Synthesizer for RF Personal

Communications

LMX2346 2.0 GHz

LMX2347 2.5 GHz

General Description

Features

n RF operation up to 2.5 GHz

n 2.7V to 5.5V operation

The LMX2346/7 are high performance frequency synthesiz-

ers with an integrated 32/33 dual modulus prescaler. The

LMX2346 is designed for RF operation up to 2.0 GHz. The

LMX2347 is designed for RF operation up to 2.5 GHz. Using

a proprietary digital phase locked loop technique, the

LMX2346/7 generates very stable, low noise control signals

for UHF and VHF voltage controlled oscillators.

n Digital & Analog Lock Detect

n 32/33 Dual modulus prescaler

n Excellent Phase Noise

n Internal balanced, low leakage charge pump

n Pin Compatible to LMX2323

Serial data is transferred into the LMX2346/7 via a three-line

MICROWIRE interface (DATA, LE, CLOCK). Supply voltage

range is from 2.7V to 5.5V. The charge pump provides 4 mA

output current.

Applications

n Cellular DCS/PCS/3G infrastructure equipment

n Wireless Local Area Networks (WLANs)

n Other wireless communication systems

The LMX2346/7 are manufactured using National’s 0.5µ

ABiC V silicon BiCMOS process and is available in 16-pin

TSSOP and 16-pin CSP packages.
