LMX2306 - Low Power Frequency Synthesizer

General 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.

LMX2306/LMX2316/LMX2326 PLLatinum Low Power Frequency Synthesizer for RF Personal Communications April 2000 LMX2306/LMX2316/LMX2326 PLLatinum™ Low Power Frequency Synthesizer for RF Personal Communications LMX2306 550 MHz LMX2316 1.2 GHz LMX2326 2.8 GHz General 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.
