s DESCRIPTION

The Fujitsu MB15F72SP 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 pres-

caler can be selected for the prescaler that enables pulse swallow operation.

MB15F72SP has the same configuration with MB15F02 or MB15F02L. The BiCMOS process is used , as a result

a supply current is typically 2.7 mA typ. 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 a area of MB15F72SP more than 30 % comparing with the former BCC16

(for dual PLL).

MB15F72SP is ideally suited for wireless mobile communications, such as PDC
