Description

The LMX2306/16/26 are monolithic, integrated frequencysynthesizers with prescalers that are designed to be used togenerate a very stable low noise signal for controlling the lo-cal oscillator of an RF transceiver. They are fabricated usingNational's ABiC V silicon BiCMOS 0.5µ process.

The LMX2306 contains a 8/9 dual modulus prescaler whilethe LMX2316 and the LMX2326 have a 32/33 dual modulusprescaler. The LMX2306/16/26 employ a digital phaselocked loop technique. When combined with a high qualityreference oscillator and loop filter, the LMX2306/16/26 pro-vide the feedback tuning voltage for a voltage controlled os-cillator to generate a low phase noise local oscillator signal.

Serial data is transferred into the LMX2306/16/26 via a threewire interface (Data, Enable, Clock). Supply voltage canrange from 2.3V to 5.5V. The LMX2306/16/26 feature ultralow current consumption; LMX2306 - 1.7 mA at 3V,LMX2316 - 2.5 mA at 3V, and LMX2326 - 4.0 mA at 3V.

The LMX2306/16/26 synthesizers are available in a 16-pin TSSOP surface mount plastic package.
