LMX2311U - PLLatinum Ultra Low Power Frequency Synthesizer

Download the LMX2311U datasheet PDF. This datasheet also covers the LMX variant, as both devices belong to the same pllatinum ultra low power frequency synthesizer family and are provided as variant models within a single manufacturer datasheet.

Description

The LMX2310/1/2/3U are high performance frequency synthesizers.

The LMX2310/1/2U use a selectable, dual modulus 32/33 and 16/17 prescaler.

The LMX2313U uses a selectable, dual modulus 16/17 and 8/9 prescaler.

LMX2310U/LMX2311U/LMX2312U/LMX2313U PLLatinum Ultra Low Power Frequency Synthesizer for RF Personal Communications June 2003 LMX2310U/LMX2311U/LMX2312U/LMX2313U PLLatinum™ Ultra Low Power Frequency Synthesizer for RF Personal Communications LMX2310U 2.5 GHz LMX2311U 2.0 GHz LMX2312U 1.2 GHz LMX2313U 600 MHz General Description The LMX2310/1/2/3U are high performance frequency synthesizers. The LMX2310/1/2U use a selectable, dual modulus 32/33 and 16/17 prescaler. The LMX2313U uses a selectable, dual modulus 16/17 and 8/9 prescaler. The device, when combined with a high quality reference oscillator and a voltage controlled oscillator, generates very stable, low noise local oscillator signals for up and down conversion in wireless communication devices.
