com FUJITSU SEMICONDUCTOR DATA SHEET DS04-21375-2E ASSP Dual Serial Input PLL Frequency Synthesizer MB15F72UV s DESCRIPTION The Fujitsu MB15F72UV 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 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 data format is the same as the previous one MB15F02SL, MB12F72SP/UL.
Fast locking is achieved for adopting the new circuit.
MB15F72UV is in the new small package (BCC18) , which decreases a mount area of MB15F72UV about 50% comparing with the former BCC20 (for dual PLL) .
MB15F72UV is ideally suited for wireless mobile communications, such as CDMA.
