MB15F83UL
s DESCRIPTION
The Fujitsu MB15F83UL is Fractional-N Phase Locked Loop (PLL) frequency synthesizer with fast lock up function.
The Fractional-N PLL operating up to 2000 MHz and the integer PLL operating up to 600 MHz are integrated on
one chip.
The MB15F83UL is used, as charge pump which is well-balanced output current with 1.5 mA and 6 mA selectable
by serial data, direct power save control and digital lock detector. In addition, the MB15F83UL adopts a new
architecture to achieve fast lock.
The new package (Thin Bump Chip Carrier20) decreases a mount area of MB15F83UL more than 30% comparing
with the former B.C.C.16 (for dual PLL, MB15F03SL) .
The MB15F83UL is ideally suited for wireless mobile communications, such as GSM.
