LMX2335U Datasheet (National Semiconductor) - Ultra Low Power Dual Frequency Synthesizer

LMX2335U, Ultra Low Power Dual Frequency Synthesizer

The LMX2335U and LMX2336U are monolithic, integrated dual frequency synthesizers, including two high frequency prescalers, and are designed for applications requiring two RF phase-lock loops.

The LMX2335U/36U contains two dual modulus prescalers.

A 64/65 or a 128/129 prescaler can be selected for ea
