MB15F72UL Overview
The Fujitsu MB15F72UL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1300 MHz and a 350 MHz prescalers. A 64/65 or a 128/129 for the 1300 MHz prescaler, and a 8/9 or a 16/17 for the 350 MHz prescaler can be selected for the prescaler that enables pulse swallow operation. The BiCMOS process is used, as a result a supply current is typically 2.5 mA at 2.7.
