LMX2301

PLLatinum

TM 160 MHz Frequency Synthesizer

for RF Personal Communications

General Description

The LMX2301 is a high performance frequency synthesizer

designed for RF operation up to 160 MHz It is fabricated

using National’s ABiC IV BiCMOS process

LMX2301 which employs the digital phase lock loop tech-

nique combined with a high quality reference oscillator and

a loop filter provides the tuning voltage for the voltage con-

trolled oscillator to generate a very stable low noise local

oscillator signal

Serial data is transferred into the LMX2301 via a three line

MICROWIRETM interface (Data Enable Clock) Supply volt-

age can range from 27V to 55V

The LMX2301 features very low current consumption typi-

cally 2 mA at 3V

The LMX2301 is available in a TSSOP 20-pin surface mount

plastic package
