LMX2305
PLLatinum
TM 550 MHz Frequency Synthesizer
for RF Personal Communications
General Description
The LMX2305 is a high performance frequency synthesizer
with an integrated prescaler designed for RF operation up to
550 MHz It is fabricated using National’s ABiC IV BiCMOS
process
The LMX2305 contains a dual modulus prescaler which can
select either a 6465 or a 128129 divide ratio at input fre-
quencies of up to 550 MHz LMX2305 which employs the
digital phase lock loop technique combined with a high
quality reference oscillator and a loop filter provides the
tuning voltage for the voltage controlled oscillator to gener-
ate a very stable low noise local oscillator signal
Serial data is transferred into the LMX2305 via a three line
MICROWIRETM interface (Data Enable Clock) Supply volt-
age can range from 265V to 55V The LMX2305 features
very low current consumption typically 40 mA at 275V
The LMX2305 is available in a TSSOP 20-pin surface mount
plastic package
