API Technologies’ Model LCFS1090 frequency synthesizer combines a monolithic integer-n microwave synthesizer, a reference
oscillator and a microcontroller to provide an economical frequency source solution. Complex serial register programming is not
required. A built-in lookup table in the microcontroller allows for simplified frequency programming with a dual 8-bit binary
frequency selection word. The LCFS1090 synthesizer is RoHS compliant, however there is a lead based solder used in the
construction of the Demo Board (if the DEMO Board is requested).
