LMX2322 PLLatinum
TM
2.0 GHz Frequency Synthesizer
for RF Personal Communications
General Description
The LMX2322 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 LMX2322’s linear phase detector characteristics
can generate very stable, low noise control signals for UHF and
VHF voltage controlled oscillators.
Serial data is transferred into the LMX2322 via a three-line
MICROWIRE
is from 2.7 V to 3.9 V. The LMX2322 features very low current
consumption, typically 3.5 mA at 3.75V. The charge pump
provides 4mA output current.
The LMX2322 is manufactured using National’s ABiC V BiCMOS
process and is packaged in a 16 pin TSSOP and a 16 pin Chip
Scale Package (CSP).
