LMX2434 - Dual High Frequency Synthesizer

Download the LMX2434 datasheet PDF. This datasheet also covers the LMX variant, as both devices belong to the same dual high frequency synthesizer family and are provided as variant models within a single manufacturer datasheet.

Description

The LMX243x devices are high performance frequency synthesizers with integrated dual modulus prescalers.

The LMX243x devices are designed for use as RF and IF local oscillators for dual conversion radio transceivers.

LMX2430/LMX2433/LMX2434 PLLatinum Dual High Frequency Synthesizer for RF Personal Communications May 2003 LMX2430/LMX2433/LMX2434 PLLatinum™ Dual High Frequency Synthesizer for RF Personal Communications LMX2430 3.0 GHz/0.8 GHz LMX2433 3.6 GHz/1.7 GHz LMX2434 5.0 GHz/2.5 GHz General Description The LMX243x devices are high performance frequency synthesizers with integrated dual modulus prescalers. The LMX243x devices are designed for use as RF and IF local oscillators for dual conversion radio transceivers. A 32/33 or a 16/17 prescale ratio can be selected for the 5.0 GHz LMX2434 RF synthesizer. An 8/9 or a 16/17 prescale ratio can be selected for both the LMX2430 and LMX2433 RF synthesizers. The IF circuitry contains an 8/9 or a 16/17 prescaler.
