DESCRIPTION
The Fujitsu MB15C03 is a serial input Phase Locked Loop (PLL) frequency synthesizer with a prescaler. A 64/
65 division is available for the prescaler that enables pulse swallow operation.
This operates with a supply voltage of 1.0 V (min.).
MB15C03 is suitable for mobile communications, such as paging systems.
