s DESCRIPTION
The Fujitsu MB15F73UL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2250 MHz and
a 600 MHz prescalers. A 64/65 or a 128/129 for the 2250 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.
The BiCMOS process is used, as a result a supply current is typically 3.2 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 date. The data format is the same as the previous one MB15F03SL, MB15F73SP. Fast locking
is achieved for adopting the new circuit.
The new package (BCC20) decreases a mount area of MB15F73UL more than 30% comparing with the former
BCC16 (for dual PLL) .
MB15F73UL is ideally suited for wireless mobile communications, such as GSM and PCS.
s FEATURES
• High frequency operation
: RF synthesizer : 2250 MHz Max.
: IF synthesizer : 600 MHz Max.
• Low power supply voltage
: VCC = 2.4 to 3.6 V
• Ultra low power supply current : ICC = 3.2 mA Typ.
(VCC = Vp = 2.7 V, Ta = +25 °C, SWIF = SWRF = 0 in IF/RF locking state)
