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.
s FEATURES
• High frequency operation : RF synthesizer : 1300 MHz Max
: IF synthesizer : 350 MHz Max
• Low power supply voltage : VCC = 2.4 V to 3.6 V
• Ultra low power supply current : ICC = 2.5 mA Typ
(VCC = 2.7 V, SWIF = SWRF = 0, Ta = +25 °C, in IF, RF locking state)
