Model # LCFS1071 750-1500 MHz Frequency Synthesizer Low Phase Noise in a Lower Cost Package Features • Low Phase Noise: -110 dBc/Hz (100 kHz offset) • External Reference Oscillator (Internal Ref. Option at No Extra Charge) • No User Programming Required • Integrated Microcontroller Look-up Table • Customized Parallel or Serial Programming Available • 3 Additional Complementary Output Lines are Available (Option) API Technologies’ Model LCFS1071 frequency synthesizer combines a monolithic integer-n microwave synthesizer, 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.
