2.8 GHz PLLatinum Low Power Frequency Synthesizer For RF Personal Communications
The LMX2306 LMX2316 LMX2326 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 0.5? 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 LMX2316 LMX2326 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 LMX2316 LMX2326 via a three wire Interface (Data, Enable, Clock). Supply voltage CAN range from 2.3V to 5.5V. The LMX2306 LMX2316 LMX2326 feature ultra low current consumption; LMX2306 - 1.7 mA at 3V, LMX2316 - 2.5 mA at 3V, and LMX2326 - 4.7 mA at 3V.
The LMX2306 16/26 synthesizers are available in a 16-pin TSSOP surface mount plastic package.
