National Semiconductor LMX2430/LMX2433/LMX2434 PLLatinum Dual High Frequency Synthesizer Datasheet
The LMX243x devices are high performance frequency synthesizers with integrated dual modulus prescalers, designed for use as RF and IF local oscillators for dual conversion radio transceivers. The family includes the LMX2430 (3.0 GHz/0.8 GHz), LMX2433 (3.6 GHz/1.7 GHz), and LMX2434 (5.0 GHz/2.5 GHz). Using a proprietary digital phase locked loop technique, these devices generate very stable, low noise control signals for RF and IF voltage controlled oscillators.
