Model # LCFS1089 (LCFS1089-DEMO) 2200 to 4400 MHz Frequency Synthesizer Low Phase Noise in a Lower Cost Package Features • Low Phase Noise: -98 dBc/Hz (100 kHz offset) • External Reference Oscillator • No User Programming Required • Integrated Microcontroller Look-up Table • Customized Parallel • EAR99, RoHS Compliant • DEMO Board available upon request. API Technologies’ Model LCFS1089 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 LCFS1089 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).

The demo board and synthesizer will be powered by the USB port. Allow Windows time to find the driver through an automatic search. A good driver installation is indicated by a flashing yellow light. 2) Go to the Windows Control Panel, find the icon “hardware and sound, devices and printers”. There should be an icon for a USB serial port. Double click on the icon, and select the “Hardware” tab of the properties window. 3) Click on the properties button. On the “General” tab click on the change settings button. Click on the “Port Settings A” tab, and then click on the advanced button. 4) In the “Advanced Settings” window, click on the “com port” button and select a high numbered “com port” that is not in use such as 11 or 12. 5) Click on the OK button 3X to close all the windows. 6) You should now have a USB com port in your hardware window with the new com number. You will use this com number in the control spreadsheet to address a particular demo board. If you install multiple demo boards be sure to give them different com numbers.
