DESCRIPTION
The Fujitsu MB15U10 is a dual serial input phase-locked loop (PLL) frequency synthesizer and is ideally suitable for mobile
communications such as cellular phones.
The MB15U10 has two PLL frequency synthesizer circuits on a single chip: one for transmission and the other for reception (PLL1
and PLL2).
It can operate from a +2.6V to 5.5V supply. Fujitsu’s advanced technology achieves an Icc of 7 mA (typical) as well as 10
(max.) at power saving mode.

FEATURES
Two PLLs’ for transmission/reception
Low current consumption
Power saving function
Divide ratio setting with serial data input :
Binary 12-bit reference counter:6 to 4,095

PACKAGE
This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields. However, it is advised that normal precautions
be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit.
