LMX2323
PLLatinum
2.0 GHz Frequency Synthesizer for RF
Personal Communications
General Description
The LMX2323 is a high performance frequency synthesizer
with integrated 32/33 dual modulus prescaler designed for
RF operation up to 2.0 GHz. Using a proprietary digital
phase locked loop technique, the LMX2323’s linear phase
detector characteristics can generate very stable, low noise
control signals for UHF and VHF voltage controlled oscilla-
tors.
Serial data is transferred into the LMX2323 via a three-line
MICROWIRE
interface (Data, LE, Clock). Supply voltage
range is from 2.7V to 5.5V. The LMX2323 features very low
curent consumption, typically 3.5mAat 3V. The charge pump
provides 4 mA output current.
The LMX2323 is manufactured using National’s ABiC V
BiCMOS process and is packaged in a 16-pin TSSOP.
