LMX2430 - Dual High-Frequency Synthesizer

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.
