Overview
Model # LCFS1055 275 to 550 MHz Frequency Synthesizer Low Phase Noise in a Lower Cost Package Features • Low Phase Noise: -116 dBc/Hz (100 kHz offset) • Fast 80 µsec Settling Speed • Internal Reference Oscillator (External Optional) • No User Programming Required • Integrated Microcontroller Look-up Table • Customized Parallel or Serial Programming Available • 3 Additional Complementary Output Lines are Available API Technologies’ Model LCFS1055 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.
Either parallel or serial programming can be accommodated.
