DESCRIPTION
The Fujitsu MB15F73SP is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2000 MHz pres-
caler and a 600 MHz prescaler. A 64/65 or a 128/129 for the 2000 MHz prescaler, and a 8/9 or a 16/17 for the 600
MHz prescaler can be selected for the prescaler that enables pulse swallow operation.
MB15F73SP has the same configuration with MB15F03 or MB15F03L. The BiCMOS process is used , as a result
a supply current is typically 3.5 mA at 2.7 V. The supply voltage range is from 2.4 V to 3.6 V. A refined charge
pump supplies well-balanced output current with 1.5 mA and 6 mA selectable by serial data.
The new package (BCC20) decreases an area of MB15F73SP more than 30 % comparing with the former BCC16
(for dual PLL).
MB15F73SP is ideally suited for wireless mobile communications, such as PDC.
