Page 1
... 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). ...
