LMX2433 - Dual High-Frequency Synthesizer

Download the LMX2433 datasheet PDF. This datasheet also covers the LMX2430 variant, as both devices belong to the same dual high-frequency synthesizer family and are provided as variant models within a single manufacturer datasheet.

General Description

Using a proprietary digital-phase, locked-loop technique, the LMX243x devices generate very stable, low-noise control signals for RF and IF voltage controlled oscillators.

Both the RF and IF synthesizers include a two-level programmable charge pump.
