MB15C100 Overview
The Fujitsu MB15C100 series is an exclusive Intermediate Frequency (IF) band Phase Locked Loop (PLL) frequency synthesizer with pulse swallow operation. It can operate maximum at 500 MHz. The reference divider and parison divider have fixed divide ratios, so that it is not required to set the divide ratios by a µcontroller externally.
