Description
The LMX2306/16/26 are monolithic, integrated frequency synthesizers with prescalers that are designed to be used to generate a very stable low noise signal for controlling the local oscillator of an RF transceiver. They are fabricated using National’s ABiC V silicon BiCMOS 0.5µ process.
The LMX2306 contains a 8/9 dual modulus prescaler while the LMX2316 and the LMX2326 have a 32/33 dual modulus prescaler. The LMX2306/16/26 employ a digital phase locked loop technique. When combined with a high quality reference oscillator and loop filter, the LMX2306/16/26 provide the feedback tuning voltage for a voltage controlled oscillator to generate a low phase noise local oscillator signal. Serial data is transferred into the LMX2306/16/26 via a three wire interface (Data, Enable, Clock). Supply voltage can range from 2.3V to 5.5V. The LMX2306/16/26 feature ultra low 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.
