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
MICROWIRE
TM
interface (Data, Enable, Clock). Supply volt-
age can range from 2.7V to 5.5V.
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.
