LMX2346/LMX2347 PLLatinum™ Frequency Synthesizer for RF Personal Communications

LMX2346 2.0 GHz

LMX2347 2.5 GHz

Check for Samples: LMX2346, LMX2347

FEATURES

DESCRIPTION

The LMX2346/7 are high performance frequency

synthesizers 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.

•

RF Operation up to 2.5 GHz

2.7V to 5.5V Operation

•

Digital & Analog Lock Detect

32/33 Dual Modulus Prescaler

Excellent Phase Noise

Internal Balanced, Low Leakage Charge Pump

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

•

Cellular DCS/PCS/3G Infrastructure Equipment

Wireless Local Area Networks (WLANs)

Other Wireless Communication Systems

The LMX2346/7 are manufactured using TI's 0.5µ

ABiC V silicon BiCMOS process and is available in

16-pin TSSOP and 16-pin LGA packages.
