Product Summary

The lmx2306 is a monolithic, integrated frequency synthesizer 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. It is fabricated using National ABiC V silicon BiCMOS 0.5μ process. The lmx2306 contains a 8/9 dual modulus prescaler. The lmx2306 employs a digital phase locked loop technique. When combined with a high quality reference oscillator and loop filter, the lmx2306 provides 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 via a three wire interface (Data, Enable, Clock). Supply voltage can range from 2.3V to 5.5V. The lmx2306 features ultra low current consumption; LMX2306TM - 1.7 mA at 3V.
