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
