The Fujitsu MB15F78SP is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2550 MHz prescaler and a 1200 MHz prescaler. A 32/33 or a 64/65 for the 2550 MHz prescaler, and a 16/17 or a 32/33 for the 1200 MHz prescaler can be selected for the prescaler that enables pulse swallow operation.
The BiCMOS process is used in MB15F78SP, as a result a supply current is typically 5.5 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 MB15F78SP more than 30 % comparing with the former BCC16 (for dual PLL).
MB15F78SP is ideally suited for wireless mobile communications, such as GSM.
