LMX2335U/LMX2336U PLLatinum Ultra Low Power Dual Frequency Synthesizer for RF Personal munications PRELIMINARY May 2001 LMX2335U/LMX2336U PLLatinum™ Ultra Low Power Dual Frequency Synthesizer for RF Personal munications LMX2335U LMX2336U 1.2 GHz/1.2 GHz 2.0 GHz/1.2 GHz General Description 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 each RF synthesizer. A second reference divider chain is included in the IC for improved system...
