The LMX2301 is a high performance frequency synthesizer designed for RF operation up to 160 MHz. It is fabricated using National's ABiC IV BiCMOS process. LMX2301, which employs the digital phase lock loop technique, combined with a high quality reference oscillator and a loop filter, provides the tuning voltage for the voltage controlled oscillator to generate a very stable, low noise local oscillator signal. Serial data is transferred into the LMX2301 via a three line MICROWIRETM interface (Data, Enable, Clock). Supply voltage can range from 2.7V to 5.5V.
The LMX2301 features very low current consumption, typically 2 mA at 3V.
The LMX2301 is available in a TSSOP 20-pin surface mount plastic package.
