LM2335 Datasheet (National Semiconductor) - PLLatinum Low Power Dual Frequency Synthesizer for RF Personal Communications

LM2335, PLLatinum Low Power Dual Frequency Synthesizer for RF Personal Communications

The LMX2335L and LMX2336L are monolithic, integrated dual frequency synthesizers, including two high frequency prescalers, and are designed for applications requiring two RF phase-lock loops.

They are fabricated using National’s 0.5µ ABiC V silicon BiCMOS process.

The LMX2335L/36L contains two dual
