Product Summary
The LMX2326TMD 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 Nationals ABiC V silicon BiCMOS 0.5μ process. The LMX2326TMD has a 32/33 dual modulus prescaler. The device employs a digital phase locked loop technique. When combined with a high quality reference oscillator and loop filter, the LMX2326TMD 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 device via a three wire interface (Data, Enable, Clock). Supply voltage can range from 2.3V to 5.5V. The LMX2326TMD synthesizer is available in a 16-pin TSSOP surface mount plastic package.
