LMX2324
PLLatinum 2.0 GHz Frequency Synthesizer for RF
Personal Communications
General Description
The LMX2324 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 LMX2324’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 LMX2324 via a three-line
MICROWIRE interface (Data, LE, Clock). Supply voltage
range is from 2.7V to 5.5V. The LMX2324 features very low
current consumption, typically 3.5 mA at 3V. The charge
pump provides 4 mA output current.
The LMX2324 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).
